Janis Louie

Janis Louie (born November 3, 1971 in San Francisco, California, U.S.A.) is a Chemistry professor and Henry Eyring Fellow at The University of Utah. Louie contributes to the chemistry world with her research in inorganic, organic, and polymer chemistry.
Schooling.
Louie received her B.S. from University of California, Los Angeles in 1993. She then moved on to get her Ph.D. from Yale University for work under Professor John Hartwig in 1998. In the years of 1998-2001 Louie was an NIH Postdoctoral Fellow at the California Institute of Technology.
Research.
Accessibility to structurally diverse organic compounds such as carbocycles and heterocycles are of great importance to the pharmaceutical and agrochemical industries. However the synthesis of these types of compounds require harsh conditions such as high temperatures and pressures. Dr. Louie's research aims to mediate these transitions via metal catalyzed reactions, mainly involving nickel catalysis. Dr. Louie and her team focuses on nickel-based systems not only because it is much less expensive than the more widely used palladium and platinum, but also because it offers a wider range of chemical activity, such as nickel, being a more electropositive transition metal which allows it to undergo oxidative addition readily; oxidize Nickel and lessens the electron density around the atom itself.6 This allows for the cross-coupling of electrophiles to occur which is pivotal in the formation of carbocycles and heterocycles. Dr. Loui and her colleagues further enhance the catalytic ability by combining nickel with N-heterocyclic carbene (NHC) ligands. The NHC ligands are largely sterically hindered and electron donating, which allows improved and less harsh reactions conditions by expanding the chemical scope of the substrate. (Taking all these chemical factors into account, the Ni/NHC catalyst can effectively couple diynes and nitriles to create pyridines using a hetero-oxidative coupling mechanism. Also, this nickel catalysis method (Figure 1) offers a wider range of substrates for which nickel can perform cyclo-additions on, substrates such as; vinylcyclopropanes, aldehydes, ketones, tropones, 3-azetidinones, and 3-oxetanones).
Louie is also involved in the study and research of diversifying organometallic catalysts. Usually, an organometallic catalyst is only used for one specific type of reaction, but Louie has been 
working on the development of these organometallic catalysts as to make them able to catalyze more than one specific type of reaction. This may be done by using the same catalyst, or by using one catalyst that can be slightly altered into making a catalyst that is useful for another type of reaction.
Louie also experimented with the production of 2-pyrones. She would use carbon dioxide mixed with different diynes to prepare different 2-pyrones. The simple reaction for the formation of 2-pyrones is shown in Figure [null 2] .
Louie's nickel imidazolyidene complexes help progress the cyclization of terminal and internal functional group like aryl and alkyl isocyanates in a rather mild manner as opposed to synthetic synthesis.
