The α-ketoacyl complexes trans-M(PPh3)2(Cl)(COCO2R) (M = Pd, R = (CH2)nCHCH2, n = 2, 3, 4, R = (CH2)2CCMe; M = Pt, R = (CH2)nCHCH2, n = 2, 3, 4, R = (CH2)2CCMe) were prepared by treating M(PPh3)4 with ROCOCOCl. Attempts to insert the pendant olefin or acetylene into the α-ketoacyl-to-metal bond through heating failed, since CO deinsertion to form corresponding acyl complexes was predominant. Reaction of [trans-Pt(PPh3)2(NCMe)(COCOR)]BF4 (R = Me, Ph) with norbornylene resulted in the deinsertion of CO from the α-ketoacyl ligand and the formation of [cis-Pt(PPh3)2(C7H10COR)]BF4, an insertion of norbornylene into the corresponding acyl ligand.
