Reactions of trans-[Pt(H2){P(C6H11)3}2] with heterocumulenes. The crystal and molecular structure of trans-[Pt{P(C6H11)3}2(H){OCH?C(C6H5)2}]

Trans-PtH2(PCy3)2 (1) reacts with phenylisocyanate (2) and with diphenylketene (3) to yield the formamido complex (4) and the vinyloxo complex (5) respectively. The structure of 5 has been determined by X-ray diffraction.
