She graduated from Yale University with a BS and MS in chemistry in 1996, having carried out research with Robert H. Crabtree, while competing for the Yale Gymnastics NCAA team. She graduated from the California Institute of Technology with a Ph.D. in 2001, where she studied Chemistry with Robert H. Grubbs. She did postdoctoral work at Princeton University, where she studied with John T. Groves. [5]
Sanford began her academic career as an assistant professor at the University of Michigan in 2003. She was promoted to associate professor with tenure in 2007 and full professor in 2013.
Sanford is best known for her studies of high-valent organopalladium species, particularly those implicated in Pd-catalyzed C–H functionalization reactions. [6] [7] Her group has also developed new methods to access fluorinated and radiofluorinated materials for agrochemicals, pharmaceuticals [8] and radiology. [9] In a collaboration with Matthew Sigman at the University of Utah her group has designed new compounds for use in redox flow batteries. [10] [11]
Sanford has received numerous awards and honors including but not limited to:
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 organic chemistry, a cross-coupling reaction is a reaction where two different fragments are joined. Cross-couplings are a subset of the more general coupling reactions. Often cross-coupling reactions require metal catalysts. One important reaction type is this:
Karen Ila Goldberg is an American chemist, currently the Vagelos Professor of Energy Research at University of Pennsylvania. Goldberg is most known for her work in inorganic and organometallic chemistry. Her most recent research focuses on catalysis, particularly on developing catalysts for oxidation, as well as the synthesis and activation of molecular oxygen. In 2018, Goldberg was elected to the National Academy of Sciences.
A stannatrane is a tin-based atrane belonging to the larger class of organostannanes. Though the term stannatrane is often used to refer to the more commonly employed carbastannatrane, azastannatranes have also been synthesized. Stannatrane reagents offer highly selective methods for the incorporation of "R" substituents in complex molecules for late-stage diversification. These reagents differ from their tetraalkyl organostannane analogues in that there is no participation of dummy ligands in the transmetalation step, offering selective alkyl transfer in Stille Coupling reactions. These transmetalating agents are known to be air- and moisture-stable, as well as generally less toxic than their tetraalkyl counterparts.
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.
Dialkylbiaryl phosphine ligands are phosphine ligands that are used in homogeneous catalysis. They have proved useful in Buchwald-Hartwig amination and etherification reactions as well as Negishi cross-coupling, Suzuki-Miyaura cross-coupling, and related reactions. In addition to these Pd-based processes, their use has also been extended to transformations catalyzed by nickel, gold, silver, copper, rhodium, and ruthenium, among other transition metals.
Jenny Yue-fon Yang is an American chemist. She is a Professor of chemistry at the University of California, Irvine where she leads a research group focused on inorganic chemistry, catalysis, and solar fuels.
Corinna S. Schindler is a Professor of Chemistry at the University of Michigan. She develops catalytic reactions with environmentally benign metals such as iron, towards the synthesis of biologically active small molecules. For her research in the development of new catalysts, Schindler has been honored with several early-career researcher awards including the David and Lucile Packard Foundation Fellowship in 2016, the Alfred P. Sloan Fellowship in 2017, and being named a member of the C&EN Talented 12 in 2017. Schindler has served on the Editorial Board of Organic and Bimolecular Chemistry since 2018.
Suzanne A. Blum is an American professor of chemistry at the University of California, Irvine. Blum works on mechanistic chemistry, most recently focusing on borylation reactions and the development of single-molecule and single-particle fluorescence microscopy to study organic chemistry and catalysis. She received the American Chemical Society's Arthur C. Cope Scholar Award in 2023.

He is Chief of Nuclear Medicine and director of the University of Michigan Positron Emission Tomography (PET) Center, and runs a research group developing new radiochemistry methodology and novel PET radiotracers.
The Stahl oxidation is a copper-catalyzed aerobic oxidation of primary and secondary alcohols to aldehydes and ketones. Known for its high selectivity and mild reaction conditions, the Stahl oxidation offers several advantages over classical alcohol oxidations.
Mark Stradiotto is a Canadian chemist. He is currently the Arthur B. McDonald Research Chair and the Alexander McLeod Professor of Chemistry in the Department of Chemistry at Dalhousie University.
Concerted metalation-deprotonation (CMD) is a mechanistic pathway through which transition-metal catalyzed C–H activation reactions can take place. In a CMD pathway, the C–H bond of the substrate is cleaved and the new C–Metal bond forms through a single transition state. This process does not go through a metal species that is bound to the cleaved hydrogen atom. Instead, a carboxylate or carbonate base deprotonates the substrate. The first proposal of a concerted metalation deprotonation pathway was by S. Winstein and T. G. Traylor in 1955 for the acetolysis of diphenylmercury. It was found to be the lowest energy transition state in a number of computational studies, was experimentally confirmed through NMR experiments, and has been hypothesized to occur in mechanistic studies.
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.

Mono-N-protected amino acid (MPAA) is a bifunctional ligand that plays a key role in C–H functionalizations by accelerating the reaction rate and imparting specified chirality into the product. Amino acids are ideal building blocks for chiral ligand synthesis due to the cost, accessibility, large variety, solubility, and inherent chirality. Naturally occurring amino acids are transformed into chiral MPAA ligands that, upon coordination to metal complexes, allow reactions to occur that are otherwise energetically unfavorable. Great strides in the development of MPAA ligands over the past two decades have led to the integral role that enantioselective catalysis now plays in complex organic synthesis.
In organic chemistry, carboboration describes an addition of both a carbon and a boron moiety to certain carbon-containing double and triple bonds, such as alkenes, alkynes, and allenes.
