The chemistry of frustrated Lewis pairs(FLPs)provides a powerful approach for meal-free hydrogenation.A widerange of unsaturated compounds have been successfully hydrogenated using FLP catalysts.However,there still remainsome unsolved problems,for example,the FLP-catalyzed asymmetric hydrogenation is only in its infancy.1 wedeveloped a novel strategy for the development of borane catalysts by the in situ hydroboration of alkenes with Piersborane HB(C6F5)2.
