reaction of aryl and vinyl boronic acids and allylic alcohols proceeded smoothly in toluene or dioxane in the presence of a (triphenyl phosphite)palladium catalyst to give the corresponding allylbenzene derivatives and 1,4-dienes. Neither cocatalysts for promoting C−O bond cleavage of allylic alcohols nor bases for activation of organoboron reagents are required for promoting the coupling process. (© Wiley-VCH
在(亚磷酸三苯酯)钯催化剂存在下,芳基和乙烯基硼酸与烯丙醇在甲苯或二恶烷中的交叉偶联反应顺利进行,得到相应的烯丙基苯衍生物和1,4-二烯。促进偶联过程不需要用于促进烯丙醇的 CO 键断裂的助催化剂和用于活化有机硼试剂的碱。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
