Preorganized frustrated Lewis pairs.
Geminal frustrated Lewis pairs (FLPs) are expected to exhibit increased reactivity when the donor and acceptor sites are perfectly aligned. This is shown for reactions of the nonfluorinated FLP tBu(2)PCH(2)BPh(2) with H(2), CO(2), and isocyanates and supported computationally.
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 کاملIntramolecular frustrated lewis pairs: formation and chemical features.
Intramolecular vicinal and geminal frustrated Lewis pairs (FLPs) featuring bulky substituents at phosphorus or nitrogen and strongly electron-withdrawing bulky pentafluorophenyl substituents at boron undergo a variety of addition and/or activation reactions with small molecules. A number of examples of such reactions are presented and discussed, among them the FLP activation of dihydrogen to gi...
متن کامل1,4-Addition reactions of frustrated Lewis pairs to 1,3-dienes.
Reactions of a frustrated Lewis pair composed of a sterically encumbered phosphine and borane are shown to react with 1,3-dienes to give the 1,4-addition products.
متن کاملReversible metal-free carbon dioxide binding by frustrated Lewis pairs.
Carbon dioxide is a gas that is changing our environment. Its role as a greenhouse gas is clear with the onset of global warming. In efforts to address this issue, ambitious and creative schemes are targeting materials including zeolites, silica gels, aluminas, and activated carbons, as well as sophisticated metal–organic frameworks (MOFs) for the benign capture and storage of carbon dioxide. A...
