摘要

Tetracoordinate vinyl nickel (II) complexes 3, 5, and 6 with square-planar geometry were obtained through the reaction of alkynes with hydrido nickel complex 1 (in situ). The reaction of 1, 4-bis (trimethylsilylethynyl) benzene afforded a monoinsertion complex, 7, while the reaction of 1, 4-bis (ethynyl) benzene through di-insertion reaction leads to a dinuclear vinyl nickel (II) complex, 8.
