“…[ 26,27 ] Thus, the capability of FLPs in small molecule activation and the hydrogen cleavage leads to their application in the hydrogenation of a large range of unsaturated substrates. [ 28 ] The combination of highly electrophilic borane‐based compounds, such as alanes, silylium ions, and especially B(C 6 F 5 ) 3 , as Lewis acids and different types of steric bulk P‐, N‐, or C‐donor Lewis bases, such as t‐Bu 3 P, Mes 3 P, lutidine, and N ‐heterocyclic carbenes, develop FLP structures, which prevent the formation of classical Lewis adducts. These compositions are mostly used for catalytic reduction reactions.…”
