A series of neutral salicylaldiminato Pd(II) complexes, Pd(Me)(Ph-CH=N-R′)[3- tBu-2-(O)-C 6H 3-CH=N-2,6-di iPr-C 6H 3] (R = CH 3, n-Pr, tert-Bu, Ph, benzyl) (3a-3e) and Pd(Me)[2-(CH=N-t-Bu)-Py][3- tBu-2-(O)C 6H 3-CH=N-2,6-di- iPr-C 6H 3] (4), have been synthesized and characterized. The structures of complexes 3a, 3c-3e, and 4 have been confirmed by X-ray analysis. NMR studies utilizing 3c indicate that the insertion of CO into the Pd-Me bond occurs through a five-coordinate intermediate. The acyl compounds in turn undergo imine insertion. The neutral complexes 3a-3e show moderate catalytic activity for the polymerization of methyl acrylate at ambient temperature. However, a radical rather than vinyl insertion mechanism appears to be operative.
