Abstract

An assembled insoluble catalyst, PdAS, prepared from palladium ((NH4) 2PdCl4 (1)) and non-cross-linked amphiphilic copolymer poly (N-isopropylacrylamide-co-4- diphenylstyrylphosphine)(2) was developed. It was found that PdAS is an excellent catalyst for the Suzuki-Miyaura reaction on three points:(1) The use of 8× 10-7 to 5× 10-4 mol equiv of PdAS afforded the coupling products efficiently after easy workup, with the turnover ...
