The objective of this study is to investigate the potential use of transition metal carbonyl complexes for the sequential insertion of CO and imines, with the ultimate goal of developing an imine/CO co-polymerization catalyst. / The reactivity of (CO)4CoMe with Tol(H)C=NMe has been investigated and evidence of imine insertion into the Co(I)-acyl bond of (CO)4Co(COMe) is observed by 1H-NMR. Attempts to generate the postulated product of Tol(H)C=NMe insertion into (CO)4Co(COMe) by addition of (CO)4Co- to Tol(H)CN(Me)COPh+Cl - led to decomposition. / The reaction of (CO)5MnR (R = Me, Ph) with imines Tol(H)C=NR '(R' = Me, Bz, Ph) yielded ortho-metallated products (CO)4Mn[2,5-C6H3(CH=NR' )(CH3)]. The reaction of (CO)5MnMe, Tol(H)C=NMe, and AlCl3 afford (CO)4Mn[CH(Tol)N(Me)C(O)Me] ( 51). Attempts to generate a CO/imine insertion product by the addition of (CO)5Mn- to Tol(H)CN(Me)COPh+Cl - yielded the new complex (CO)4Mn[C(O)CH(Tol)N(Me)C(O)Ph] (54), incorporating an inserted CO into the Mn-R bond. The x-ray crystal structure of (54), and (PPh3)(CO)3Mn[CH(Tol)N(Me)C(O)Ph] (61) were obtained and are discussed.
