16-electron state, while 2 exists in dinuclear states. Catalyst 1 converted PA less than 1% in the absence of triethylamine (Et3N). Addition of Et3N and extension of the polymerization time enhanced the monomer conversion. On the other hand, catalysts 2 and 3 quantitatively converted PA in the absence of Et3N to afford the polymer in good yields. Catalyst 3 achieved two-stage polymerization of PA.
