Abstract
Treatment of alkynylsilanes with triarylantimony diacetates in the presence of Pd-2(dba)(3). CHCl3 (5 mol%) and CuI (10 mol%) in CH3CN at 50 degreesC for 5 h afforded aryl-substituted alkynes in good yield. Alternatively, dir ect carbonylative coupling of triarylantimony diacetates with alkynylsilane s was accomplished under atmospheric pressure of carbon monoxide.
