Marta Catellani is an Italian chemist known for her discovery of the eponymous Catellani reaction in 1997. She was elected to the European Academy of Sciences in 2016. Catellani earned her Ph.D. in chemistry in 1971 from the University of Parma, where, as of 2019, she is a professor and chairs the Department of Organic Chemistry. [1] [2] [3]

Catellani completed her postdoctoral education at the University of Chicago. She has served as a visiting professor at Moscow State University (1992), Beijing Institute of Technology (2004), and University of Xi'an (2004). She was awarded a fellowship at the Japan Society for the Promotion of Science in 2012. [2] [3]

Her research focuses on palladium as a catalyst for multistep organic reactions. [2] [3]

The Catellani Reaction

In chemistry there is a practice known as synthesis. This process is used to form complex chemical compounds from simpler ones. These complex compounds are desirable for their ranging abilities and properties. In order to produce the complex compounds, the simpler ones must “cooperate” in a specific way. This can be very difficult and requires patience, because of the time required to make the bonds so their uses and properties can be tested. There was a need for optimization of this process in order to speed up the development and testing of new compounds. Catellani and her team in 1997 found such a method to optimize this process. [4] Catellani discovered a chain reaction process that simplified and increased yield for desirable complex compounds. [5] One bond the Catellani Reaction is heavily used to create is Carbon-Carbon bonds. [6] These bonds are desirable for their stability and strength. [7] These qualities make the bonds very useful in the makeup of more complex compounds. [5]

Since its discovery, the Catellani Reaction has opened the door to other discoveries or improvements in chemistry. Specifically in the world of pharmaceuticals, the Catellani Reaction has been a useful tool for synthesizing drugs in a more efficient way to aid in their development. Lenoxipen is an example of one of the complex compounds now much easier to achieve with the discovery of Catellani Reactions. [8] This compound belongs to a group of compounds known as Lignans that are useful for relieving pain and may provide benefits to cancer patients. [8] These examples of the uses for Catellani Reactions show the vast and indirect benefits to its discovery. To chemists, the Catellani Reaction is a tool that acts to optimize the process for making new compounds. These new compounds are pivotal for advancing what is possible through chemistry. As new scientists study and try to build upon the Catellani Reaction, it is important to remember who provided the first understanding as it would open up a new world of opportunity.

Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. Study of structure determines their structural formula. Study of properties includes physical and chemical properties, and evaluation of chemical reactivity to understand their behavior. The study of organic reactions includes the chemical synthesis of natural products, drugs, and polymers, and study of individual organic molecules in the laboratory and via theoretical study.

<span class="mw-page-title-main">Organometallic chemistry</span> Study of organic compounds containing metal(s)

Organometallic chemistry is the study of organometallic compounds, chemical compounds containing at least one chemical bond between a carbon atom of an organic molecule and a metal, including alkali, alkaline earth, and transition metals, and sometimes broadened to include metalloids like boron, silicon, and selenium, as well. Aside from bonds to organyl fragments or molecules, bonds to 'inorganic' carbon, like carbon monoxide, cyanide, or carbide, are generally considered to be organometallic as well. Some related compounds such as transition metal hydrides and metal phosphine complexes are often included in discussions of organometallic compounds, though strictly speaking, they are not necessarily organometallic. The related but distinct term "metalorganic compound" refers to metal-containing compounds lacking direct metal-carbon bonds but which contain organic ligands. Metal β-diketonates, alkoxides, dialkylamides, and metal phosphine complexes are representative members of this class. The field of organometallic chemistry combines aspects of traditional inorganic and organic chemistry.

Dynamic covalent chemistry (DCvC) is a synthetic strategy employed by chemists to make complex supramolecular assemblies from discrete molecular building blocks. DCvC has allowed access to complex assemblies such as covalent organic frameworks, molecular knots, polymers, and novel macrocycles. Not to be confused with dynamic combinatorial chemistry, DCvC concerns only covalent bonding interactions. As such, it only encompasses a subset of supramolecular chemistries.

Organofluorine chemistry describes the chemistry of the organofluorines, organic compounds that contain the carbon–fluorine bond. Organofluorine compounds find diverse applications ranging from oil and water repellents to pharmaceuticals, refrigerants, and reagents in catalysis. In addition to these applications, some organofluorine compounds are pollutants because of their contributions to ozone depletion, global warming, bioaccumulation, and toxicity. The area of organofluorine chemistry often requires special techniques associated with the handling of fluorinating agents.

Physical organic chemistry, a term coined by Louis Hammett in 1940, refers to a discipline of organic chemistry that focuses on the relationship between chemical structures and reactivity, in particular, applying experimental tools of physical chemistry to the study of organic molecules. Specific focal points of study include the rates of organic reactions, the relative chemical stabilities of the starting materials, reactive intermediates, transition states, and products of chemical reactions, and non-covalent aspects of solvation and molecular interactions that influence chemical reactivity. Such studies provide theoretical and practical frameworks to understand how changes in structure in solution or solid-state contexts impact reaction mechanism and rate for each organic reaction of interest.

The Catellani reaction was discovered by Marta Catellani and co-workers in 1997. The reaction uses aryl iodides to perform bi- or tri-functionalization, including C-H functionalization of the unsubstituted ortho position(s), followed a terminating cross-coupling reaction at the ipso position. This cross-coupling cascade reaction depends on the ortho-directing transient mediator, norbornene.

In organic chemistry, the Fujiwara–Moritani reaction is a type of cross coupling reaction where an aromatic C-H bond is directly coupled to an olefinic C-H bond, generating a new C-C bond. This reaction is performed in the presence of a transition metal, typically palladium. The reaction was discovered by Yuzo Fujiwara and Ichiro Moritani in 1967. An external oxidant is required to this reaction to be run catalytically. Thus, this reaction can be classified as a C-H activation reaction, an oxidative Heck reaction, and a C-H olefination. Surprisingly, the Fujiwara–Moritani reaction was discovered before the Heck reaction.

<span class="mw-page-title-main">Mizoroki-Heck vs. Reductive Heck</span>

The Mizoroki−Heck coupling of aryl halides and alkenes to form C(sp2)–C(sp2) bonds has become a staple transformation in organic synthesis, owing to its broad functional group compatibility and varied scope. In stark contrast, the palladium-catalyzed reductive Heck reaction has received considerably less attention, despite the fact that early reports of this reaction date back almost half a century. From the perspective of retrosynthetic logic, this transformation is highly enabling because it can forge alkyl–aryl linkages from widely available alkenes, rather than from the less accessible and/or more expensive alkyl halide or organometallic C(sp3) synthons that are needed in a classical aryl/alkyl cross-coupling.

Organotechnetium chemistry is the science of describing the physical properties, synthesis, and reactions of organotechnetium compounds, which are organometallic compounds containing carbon-to-technetium chemical bonds.
