  The synthesis and molecular structure of the zero-valent platinum-mono-carbene-bis-alkene complexes [Pt-0(NHC)(dimethyl fumarate)(2)] (NHC = 1,3-dimesityl-imidazol-2-ylidene (1a); 1,3-dimesityl-dihydroimidazol-2-ylidene (2a); diphenyl-dihydroimidazol-2-ylidene (2b) are described. Two routes have been evaluated for the synthesis of la and 2a, involving reaction of a zero-valent platinum compound either with an isolated carbene ligand, or with an in situ generated carbene ligand. The in situ method proved to be easier and gave similar yields of about 50% after crystallization. Attempts have been made to synthesize similar compounds with N-phenyl and N-alkyl groups, of which the latter met with little success. However, (1,3-diphenyl-dihydroimidazol-2-ylidene)-bis(eta(2)-dimethyl fumarate) platinum(0) (2b) could be obtained in 49% yield, after crystallization, from the appropriate Wanzlick dimer.Compound la reacts with H-2 and D-2 in sequences of oxidative addition, migration-insertion involving dimethyl fumarate, and reductive elimination to form neutral hydrido platinum (11) carbene complexes, probably containing a metallacyclic (R)-C=O...Pt unit.
