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 platinum-oxygen 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.

Abstract
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 platinum-oxygen 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.
