摘要

Novel ionic Ni (II) complexes of general formula [R2im][Ni (PPh3) Cl3](R2im= 1, 3-bis (2, 6- diisopropylphenyl) imidazolium cation, IPrim, 1a; R2im= 1, 3-diisopropylimidazolium cation, iPrim, 2a) were easily prepared in high yields by the direct reaction of Ni (PPh3) 2Cl2 with 1 equiv. of N, N′-dihydrocarbylimidazolium salt,[R2im] Cl. Their bromide analogs [R2im][Ni (PPh3) Br3](R2im= IPrim, 1b; R2im= iPrim, 2b) were synthesized by the same reaction in ...
