Ni(cod)(PMe{sub 3}){sub 2} and the o-, m-, and p- bromobenzyl bromides react, under appropriate conditions, to afford the binuclear complexes Ni{sub 2}({mu}{sub 2}-{eta}{sup 3}, {eta}{sub 1}CH{sub 2}C{sub 6}H{sub 4})Br{sub 2}(PMe{sub 3}){sub 3} (1a-c) or Ni{sub 2}({mu}{sub 2}-{eta}{sup 1}, {eta}{sup 1}-CH{sub 2}C{sub 6}H{sub 4})Br{sub 2}{sup {minus}}(PMe{sub 3}){sub 4} (2b,c). The reaction of the ortho {eta}{sup 3}-benzylic derivative 1a with isocyanides, CNR, has been investigated, and three different isomeric species have been identified for R - Bu{sup t}. The CNC{sub 6}H{sub 3}-2,6-Me{sub 2}-vinyl complex 7 derived from the N-aryl-1-isoquinolone 8, which can be freed by hydrolytic cleavage of the Ni-vinyl bond. 17 refs.
