Abstract
Abstract Tris(pentafluorophenyl)borane [B(C 6 F 5 ) 3 ] has found to be an efficient catalyst for Friedel–Crafts reactions between activated arenes or heteroarenes and α-amidosulfones. The products undergo further Friedel–Crafts reactions with activated heteroarenes leading to the synthesis of unsymmetrical triarylmethanes. The present synthetic method displayed significant advantages such as low catalyst loading, mild reaction conditions, highly regioselective, high yield, and broad applicability to various substrates.
