A range of alkenylboronic acids undergo Suzuki cross-coupling with aryl bromides in good yields in the presence of [PdCl(C3H5)]2/cis,cis,cis-1,2,3,4-tetrakis[(diphenylphosphanyl)methyl]cyclopentane as a catalyst. A wide variety of 1-arylprop-1-enes, 2-arylprop-1-enes, 2-arylbut-1-enes and 1,1-diarylethylene or styrene derivatives have been prepared. Moreover, the reaction tolerates several functions
在 [PdCl(C3H5)]2/cis,cis,cis-1,2,3,4-四[(二苯基膦基)甲基]环戊烷存在下,一系列烯基硼酸与芳基溴化物以良好的收率进行 Suzuki 交叉偶联作为催化剂。已经制备了多种 1-芳基丙-1-烯、2-芳基丙-1-烯、2-芳基丁-1-烯和1,1-二芳基乙烯或苯乙烯衍生物。此外,该反应耐受多种功能,例如乙酰基、甲酰基、腈或硝基。此外,这种催化剂可以在低负载下使用,甚至用于空间位阻底物的反应。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
