Abstract: | N, N-bis(pyrazol-1-ylmethyl)aminomethane (bpam) and N, N-bis(3, 5-dimethylpyrazol-1-ylmethyl)aminomethane (bdmpam) reacted with M(CO)6 or M(CO)3(CH3CN)3 in acetonitrile to give respectively fac-(bpam)M(CO)3 and fac-(bdmpam)M(CO)3 in good yields (M=Cr, Mo, W). These complexes are characterized by elemental analysis, IR, and NMR and compared with the related polypyrazolylborate complexes of the group VI metal carbonyls. |
