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 alpha-diketones or benzoins in moderate yields, while the cross-coupling reaction gave 1,2,2-triaryl ethanones in good yields.
