摘要

Abstract Two palladium catalysts obtained in reaction of Pd (OAc) 2 with differently substituted triazolyl polysiloxanes were used in the Suzuki–Miyaura cross-coupling of aryl bromides with phenylboronic acid. Catalytic reactions, performed at 60 C in a 2-propanol- water mixture, led to high yields of cross-coupling products when 2-and 4-bromotoluene, bromobenzene, and 2-bromoanisole were used as substrates. In recycling experiments, ...
