Design of frustrated Lewis pair catalysts for metal-free and selective hydrogenation*
After a short introduction to place our work in a proper context, this account summarizes our theoretical and synthetic results in the field of frustrated Lewis pair (FLP) chemistry.
متن کاملFacile Protocol for Water-Tolerant “Frustrated Lewis Pair”-Catalyzed Hydrogenation
Despite rapid advances in the field of metal-free, "frustrated Lewis pair" (FLP)-catalyzed hydrogenation, the need for strictly anhydrous reaction conditions has hampered wide-scale uptake of this methodology. Herein, we report that, despite the generally perceived moisture sensitivity of FLPs, 1,4-dioxane solutions of B(C6F5)3 actually show appreciable moisture tolerance and can catalyze hydro...
متن کاملFrustrated Lewis pair chemistry.
Frustrated Lewis pair (FLP) chemistry, a concept that has emerged in the last decade, presents unique systems capable of metal-free hydrogenation by using simple combinations of cooperative main group element components. This finding is particularly interesting given that hydrogenation is a chemical reaction that is performed on a huge scale worldwide with current technologies relying on metal-...
متن کاملEnantioselective hydrogenation with chiral frustrated Lewis pairs.
The development of transition-metal-catalyzed asymmetric hydrogenation could be stated as the cradle of modern enantioselective catalysis. Since the early asymmetric hydrogenation example from Knowles and Sabacky in 1968, the method has rapidly advanced over the years into an important tool in academia and chemical industry. In general, for these transformations the development of effective tra...
متن کاملCyclopropane formation under frustrated Lewis pair conditions.
Reaction of the -CH2OSiMe3 substituted allyldimesitylphosphane 5 with HB(C6F5)2 resulted in a hydroboration/(C6F5)2BOSiMe3 elimination sequence to give the phosphinomethyl substituted cyclopropane derivative , probably via a phosphiranium type intermediate. Addition of B(C6F5)3 to compound gave the stable phosphiranium/borate zwitterion that was isolated and characterized by X-ray diffraction.
