  Synthesis and characterization of bifunctional trans-(Ph3P)2Pt(CO2Me)(X) complexes

  摘要：

  A series of trans-(Ph(3)P)(2)Pt(X)(Y) complexes (X = CO(2)Me or CO; Y = CO(2)Me, CO, OMe, OTf) has been prepared in order to determine the compatibility of electrophilic (CO, CO(2)Me) and nucleophilic (OH, OMe) ligands in the same platinum coordination sphere. Dealkoxylation of CO(2)Me complexes by trimethylsilyl triflate affords the corresponding cationic carbonyl derivatives, and represents a potentially useful metalloester deprotection method for controlling the formation of dimetalloester linkages. The crystal structure of [trans-(Ph(3)P)(2)Pt(CO(2)Me)(CO)]BF4 has been determined, and reveals an unusual distortion of the P-Pt-P angle perpendicular to the square planar coordination geometry. Attempted condensation reactions between trans-(Ph(3)P)(2)Pt(CO(2)Me)(CO)(+) and trans-(Ph(3)P)(2)Pt(CO(2)Me)(OH) did not yield a dimetalloester condensation product, presumably due to the steric bulk of the ancillary Ph(3)P ligands.
