Mizoroki-Heck and Sonogashira cross-couplings catalyzed by CNC palladium pincer complexes in organic and aqueous media

摘要

The catalytic activity of two CNC palladium pincer complexes is evaluated in two fundamental C - C bond-forming reactions: Mizoroki - Heck and Sonogashira cross-couplings. After several optimization attempts and a brief comparison with a PCN pincer catalyst, a number of arylated alkenes and diarylethynes are synthesized by procedures based on the catalytic use of the above mentioned CNC Pd pincers in H _2O and DMF.
