An efficient metal-free reduction using diphenylsilane with (tris-perfluorophenyl)borane as catalyst

An efficient metal-free reduction of various CX (X = O, N, C) bonds to their corresponding amines or hydrocarbons using the Ph2SiH2/B(C6F5)3 catalytic system is demonstrated. This protocol reduces enamines, enol esters, carbonyls, amides, and isocyanates.
