Connie C. Lu is a Taiwanese-American inorganic chemist and a professor of chemistry at the University of Minnesota, Twin Cities. [1] Lu's research focuses on the synthesis of novel bimetallic coordination complexes, [2] as well as metal-organic frameworks. These molecules and materials are investigated for the catalytic conversion of small molecules like as N2 and CO2 into value-added chemicals like ammonia and methanol. Lu is the recipient of multiple awards for her research, including the National Science Foundation CAREER Award [3] and the Sloan Research Fellowship [4] in 2013, and an Early Career Award from the University of Minnesota's Initiative for Renewable Energy and the Environment in 2010. [5]
Lu grew up in Miami, Florida, the daughter of immigrants from Taiwan. [6] She studied chemistry at the Massachusetts Institute of Technology, earning her B.S. in 2000. [1] As an undergraduate, she conducted research under Prof. Vernon Ingram on peptides that ameliorate amyloid beta neurotoxicity. [7]
She then went on to graduate studies at the California Institute of Technology, where she studied novel coordination chemistry and small molecule reactivity with Prof. Jonas C. Peters. Lu's doctoral work focused on the reactivity of zwitterionic palladium(II) complexes with CO, ethylene and amines, [8] [9] as well as tetrahedral manganese complexes [10] and reductive cleavage of CO2 with an iron(I) complex. [11] She earned her Ph.D. in 2006, with a thesis entitled The Chemistry of Tris(phosphino)borate Manganese and Iron Platforms. [12]
Lu conducted postdoctoral studies at the Max Planck Institute for Bioinorganic Chemistry from 2006 to 2009, under the mentorship of Prof. Karl Wieghardt. Under Wieghardt, Lu studied first-row transition metal complexes synthesized with redox non-innocent α-iminopyridine ligands. [13] [14] [15] Lu also reported the synthesis and characterization of a chromium iminyl radical complex, using the α-iminopyridine ligand system. [16]
In 2009, Lu began her independent career at the University of Minnesota, Twin Cities as an assistant professor in the department of chemistry. [18] She was promoted to associate professor with tenure in 2015, and full professor in 2020. [18]
Her research focuses on the synthesis and characterization of bimetallic complexes, especially those that contain a metal-metal bond. The Lu group has developed a series of trianionic, tripodal ligands that can coordinate two metals at close proximity, allowing for the formation for a metal-metal bond in a coordination complex. [2] The metal-metal bond order can range from bond orders of less than one to a quintuple bond, as between manganese and chromium in a complex reported in 2013, [17] and between two chromium atoms in a complex reported in 2015. [19]
These coordination complexes are also active for catalytic reactions of small molecules, such as the silylation of nitrogen by a dicobalt complex, [20] and alkene hydrogenation by nickel-group 13 element complexes. [21]
Lu was named an Outstanding Reviewer of the journal Chemical Society Reviews in 2018 [22] and 2019, [23] featured in a 2018 JACS Young Investigators Virtual Issue, [24] and named a Kavli Frontiers of Science Fellow in 2013. [25] She has been honored with invited speaking engagements, as she gave a plenary lecture at a Royal Society of Chemistry Dalton Conference in 2018, [26] and the Association for Cultural Diversity in Chemistry Lecture at the University of Pennsylvania in 2016. [27] In 2017, Lu was invited to be a speaker at the Indo-US Workshop on Organometallic Chemistry [28] and a Inorganic Chemistry Young Outstanding Upcoming speaker at Symposium on Advanced Biological Inorganic Chemistry in Kolkata, India. [29]
Lu is a member of the American Chemical Society and the Royal Chemical Society, [18] and has served on the editorial advisory board of Chemical Society Reviews since 2016. [30] She also served on the Inorganic Chemistry editorial advisory board from 2016 to 2018. [18]
Chromium hexacarbonyl (IUPAC name: hexacarbonylchromium) is a chromium(0) organometallic compound with the formula Cr(CO)6. It is homoleptic complex, which means that all the ligands are identical. It is a white, air-stable solid with a high vapor pressure.
Robert Howard Crabtree is a British-American chemist. He is serving as Conkey P. Whitehead Professor Emeritus of Chemistry at Yale University in the United States. He is a naturalized citizen of the United States. Crabtree is particularly known for his work on "Crabtree's catalyst" for hydrogenations, and his textbook on organometallic chemistry.
In chemistry, a (redox) non-innocent ligand is a ligand in a metal complex where the oxidation state is not clear. Typically, complexes containing non-innocent ligands are redox active at mild potentials. The concept assumes that redox reactions in metal complexes are either metal or ligand localized, which is a simplification, albeit a useful one.
The Liebeskind–Srogl coupling reaction is an organic reaction forming a new carbon–carbon bond from a thioester and a boronic acid using a metal catalyst. It is a cross-coupling reaction. This reaction was invented by and named after Jiri Srogl from the Academy of Sciences, Czech Republic, and Lanny S. Liebeskind from Emory University, Atlanta, Georgia, USA. There are three generations of this reaction, with the first generation shown below. The original transformation used catalytic Pd(0), TFP = tris(2-furyl)phosphine as an additional ligand and stoichiometric CuTC = copper(I) thiophene-2-carboxylate as a co-metal catalyst. The overall reaction scheme is shown below.
Transition metal carbyne complexes are organometallic compounds with a triple bond between carbon and the transition metal. This triple bond consists of a σ-bond and two π-bonds. The HOMO of the carbyne ligand interacts with the LUMO of the metal to create the σ-bond. The two π-bonds are formed when the two HOMO orbitals of the metal back-donate to the LUMO of the carbyne. They are also called metal alkylidynes—the carbon is a carbyne ligand. Such compounds are useful in organic synthesis of alkynes and nitriles. They have been the focus on much fundamental research.
Gregory S. Girolami is the William H. and Janet G. Lycan Professor of Chemistry at the University of Illinois at Urbana-Champaign. His research focuses on the synthesis, properties, and reactivity of new inorganic, organometallic, and solid state species. Girolami has been elected a fellow of the American Association for the Advancement of Science, the Royal Society of Chemistry, and the American Chemical Society.
Organotantalum chemistry is the chemistry of chemical compounds containing a carbon-to-tantalum chemical bond. A wide variety of compound have been reported, initially with cyclopentadienyl and CO ligands. Oxidation states vary from Ta(V) to Ta(-I).
In chemistry, compounds of palladium(III) feature the noble metal palladium in the unusual +3 oxidation state (in most of its compounds, palladium has the oxidation state II). Compounds of Pd(III) occur in mononuclear and dinuclear forms. Palladium(III) is most often invoked, not observed in mechanistic organometallic chemistry.

Nontrigonal pnictogen compounds refer to tricoordinate trivalent pnictogen compounds that are not of typical trigonal pyramidal molecular geometry. By virtue of their geometric constraint, these compounds exhibit distinct electronic structures and reactivities, which bestow on them potential to provide unique nonmetal platforms for bond cleavage reactions.
Julia A. Kovacs is an American chemist specializing in bioinorganic chemistry. She is professor of chemistry at the University of Washington. Her research involves synthesizing small-molecule mimics of the active sites of metalloproteins, in order to investigate how cysteinates influence the function of non-heme iron enzymes, and the mechanism of the oxygen-evolving complex (OEC).
Metal-ligand cooperativity (MLC) is a mode of reactivity in which a metal and ligand of a complex are both involved in the bond breaking or bond formation of a substrate during the course of a reaction. This ligand is an actor ligand rather than a spectator, and the reaction is generally only deemed to contain MLC if the actor ligand is doing more than leaving to provide an open coordination site. MLC is also referred to as "metal-ligand bifunctional catalysis." Note that MLC is not to be confused with cooperative binding.

A molecular electron-reservoir complex is one of a class of redox-active systems which can store and transfer electrons stoichiometrically or catalytically without decomposition. The concept of electron-reservoir complexes was introduced by the work of French chemist, Didier Astruc. From Astruc's discoveries, a whole family of thermally stable, neutral, 19-electron iron(I) organometallic complexes were isolated and characterized, and found to have applications in redox catalysis and electrocatalysis. The following page is a reflection of the prototypal electron-reservoir complexes discovered by Didier Astruc.
