摘要

Treatment of alkynylsilanes with triarylantimony diacetates in the presence of Pd 2 (dba) 3· CHCl 3 (5 mol%) and CuI (10 mol%) in CH 3 CN at 50 C for 5 h afforded aryl-substituted alkynes in good yield. Alternatively, direct carbonylative coupling of triarylantimony diacetates with alkynylsilanes was accomplished under atmospheric pressure of carbon monoxide.
