Under nitrogen atmosphere,a simple and efficient procedure for the synthesis of symmetri-cal triarylbismuth or triarylstine has been developed by reactiing aryl or alkyl bromides and magnesium (4.5 equiv)with BiCl3 or SbCl3 (1.0 equiv)in the absence of catalyst and ligand in THF at 65 ℃ for 10 h.Under air atmosphere,a series of synthesized triarylstibines has been applied in the catalyzed oxidative reaction of benzoin into benzyl.The effects of electronic and steric hindrance of substituents on the reac-tion have been discussed according to the reaction times and yields.
