ALKOXO AND HYDROXO COMPLEXES OF PLATINUM(II) - NOVEL INSERTION REACTIONS INTO PLATINUM-OXYGEN BONDS AND CONDENSATIONS WITH COMPOUNDS CONTAINING ACTIVE HYDROGEN-ATOMS

Hydroxo and alkoxo alkyl complexes of the general formula cis- and transPt(OR)(Rx)L2 (R = H, CH3; Rx = CH2CN, CF3, CH2CF3; L2 = 2 PPh3, diphosphine) were prepared by metathesis of PtCl(Rx)L2 or [Pt(Rx)L2]BF4 with NaOR. The platinumoxygen bonds undergo facile insertion of CO, COS, CS2 and SO2. The hydroxo complexes react with a variety of acids, including fairly weak carbon or nitrogen acids, such as phenylacetylene, acetamide and methylaniline, to give the corresponding condensation complexes. © 1979.
