+BF4- (1) and (R3P)2Pt(Cl)OSO2CF3 (2) have been prepared by abstraction of chloride from cis-(R3P)2PtCl2 using tetrafluoroboric acid or trifluoromethanesulfonic acid, respectively.The protons of the aqua ligand in 1 form hydrogen bridges to the BF4- anion.The acidic complexes 1 and 2 are useful starting materials for new platinum(II) complexes.HCO3- neutralizes 1 to form the carbonato complex (Et3P)2PtO2CO (5).The heterogenous reaction of 2a with glycinate gives the cationic chelate complex (6).The coordinated water of 1 is easily substituted by other ligands, e.g. phosphanes.The chloro-bridged complexes 2+ are formed by treatment of 1 or 2 with ethers.
