▎ 摘 要
In this study, cyclometallated palladium complexes, [Pd(C-N)Cl(L)), in which CN = N(1), C(2')-chelated deprotonated 2-phenylpyridine, ppy, and L = dmso (dimethylsulfoxide) (complex 1) or PPh3 (complex 2), have been synthesized. Also, complex 1 attached to amine functionalized graphene oxide (1-f-GO) has been synthesized by covalently bonding of complex 1 onto the graphene oxide surface through coordination interaction with 3-(aminomethyl)pyridine ligand spacers. The supported catalyst showed enhanced catalytic performance towards Suzuki Miyaura reaction of aryl halides and phenylboronic acid at room temperature compared with the homogeneous analogues, and they could be readily recycled and reused several times without discernible loss of their activity.
