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.
