The cis,cis,cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane-[PdCl(C3H5)]2 systemcatalyses efficiently the Suzuki cross-coupling reaction of benzylichalides with arylboronic acids. A wide variety of benzylic bromidesor chlorides and functionalised arylboronic acids lead selectivelyto the corresponding diarylmethane adducts in good yields. Furthermore,this catalyst can be used at low loading in many cases.
cis,cis,cis-1,2,3,4-四(二苯基膦甲基)环戊烷-[PdCl(C3H5)]2系统高效催化苄基卤化物与芳基硼酸的Suzuki交叉偶联反应。广泛多样的苄基溴化物或氯化物和功能化芳基硼酸选择性地生成相应二芳基甲烷加合物,产率高。进一步地,该催化剂在许多情况下可以以低负载量使用。
