摘要

Abstract trans-Bis (1, 4-dimesityl-3-methyl-1, 2, 3-triazol-5-ylidene) palladium (II) dichloride has been shown to be an excellent catalyst for the multiple Suzuki–Miyaura coupling reactions of polybromoarenes to the corresponding fully substituted polyarylarenes. The reactions proceeded in excellent yields and with high turnover numbers. With 1, 4- dibromobenzene the catalyst was found to be active for up to 13 consecutive cycles with a ...
