文摘

Metal-free catalytic C–H silylation of a series of aromatic compounds such as N,N-disubstituted anilines with various hydrosilanes has been achieved for the first time using commercially available B(C₆F₅)₃ as a catalyst. This protocol features simple and neutral reaction conditions, high regioselectivity, wide substrate scope (up to 40 examples), Si–Cl bond compatibility, and no requirement for a hydrogen acceptor.
