Abstract
Abstract The self-coupling reaction of N-acylbenzotriazoles and their cross-coupling with diarylketones promoted by Sm/TiCl4 system were investigated. Self-coupling reaction could afford α-diketones or benzoins in moderate yields, while the cross-coupling reaction gave 1, 2, 2-triaryl ethanones in good yields.
