摘要
A simple and mild protocol for the direct deoxygenative coupling of aryl ketones with electron-rich (hetero) arenes to construct the C(sp2)- 2 )- C(sp3) 3 ) bond was achieved, which was mediated by TiCl4 4 and by using ammonia borane (AB) as the reductant. This strategy provides a novel protocol for the synthesis of unsymmetrical diaryland triarylmethanes.
