Treatment of the complexes cis- (L = = donor ligand) with either N,N'-diphenylsulfamide or N,N',P-triphenylphosphonic diamide in the presence of an excess of silver(I) oxide in refluxing dichloromethane yielded the new metallacycles L2> and L2> respectively.The X-ray crystal structure of (cod)> (cod = cycloocta-1,5-diene) showed the presence of an entirely flat four-membered ring, whereas that of (PPh3)2> exhibits a small puckering angle, but with no substantial Pt...P transannular interaction. tert-Butyl isocyanide displaces a phosphine ligand from (PPh3)2>.
