摘要：

(eta(5)-Cyclopentadienyl)nickel-alkynyl complexes, CpNi(PPh3)C=CR (R = Ph, H, CO2Et), and -methyl complex effectively catalyze the polymerization of aryl isocyanides at room temperature. Double-insertion complexes of isocyanides are isolated and characterized as an active intermediate of the polymerization, whose mechanism involving successive insertion of isocyanides into nickel-carbon sigma-bonds is proposed.
