Cyclopalladated and cycloplatinated complexes, which incorporated the N,N-dimethylbenzylamine and N,N-dimethylnaphthylamine motifs, were successfully employed to promote a series of intermolecular monoinsertion reactions of diphenyl-1-propynylarsane, Ph2AsC≡CMe, into the Pd–C bond of the chiral α-methyl N,N-dimethylbenzylamine palladacycles. The precursor complexes were prepared by means of the coordination of
包含 N,N-二甲基苄胺和 N,N-二甲基萘胺基序的环钯化和环铂化配合物被成功地用于促进二苯基-1-丙炔芳烃 Ph2AsC≡CMe 与 Pd-C 键的一系列分子间单插入反应。手性α-甲基N,N-二甲基苄胺钯环。前体配合物是通过将 Ph2AsC≡CMe 部分配位到金属中心与环金属化配合物的苄胺或萘胺 -N 供体原子上而制备的。随后在这些前体配合物和对映体纯的 N,N-二甲基苄胺钯环之间进行了一系列单插入反应。这些插入反应在温和条件下显示出高区域选择性,并形成了各种同和异双金属砷官能化配合物。单插入产物的配位化学和绝对立体化学由 X 射线晶体学确定。
