摘要

Abstract Short and versatile syntheses of reusable diarylphosphinopolystyrene-supported palladium catalysts 3a–j are described. The bis (o-tolyl) phosphino catalyst 3b is particularly efficient for the Suzuki and Sonogashira cross-couplings, whereas the bis (m-tolyl) phosphino catalyst 3c is the most active catalyst for Heck reactions. The couplings are performed under non-anhydrous reaction conditions and require only low amounts of ...
