Pd(OAc)₂/DABCO as an Inexpensive and Efficient Catalytic System for Hiyama­ Cross-Coupling Reactions of Aryl Halides with Aryltrimethoxysilanes

Abstract

Pd(OAc)₂/DABCO was found to be an inexpensive and efficient catalyst system for Hiyama cross-coupling reactions of aryl halides with aryltrimethoxysilanes. In the presence of Pd(OAc)₂, DABCO, and TBAF, coupling of a number of aryl halides with aryltrimethoxysilanes underwent efficiently to afford the corresponding cross-coupled products in moderate to excellent yields.

Key words

Pd(OAc)₂ - DABCO - Hiyama cross-coupling reaction - aryl halide - aryltrimethoxysilane
