Complex compounds of phosphorous esters Communication 2. Complex compounds with platinous salts

Abstract

1. Compounds of the general formula PtCl2·2P(OR)3, where R = CH3, C2H5, C3H7-i, and C6H5, have been prepared by the action of platinous chloride on trialkyl phosphites, and some of their properties have been studied. The methyl and ethyl compounds were found to be identical with the complexes o tained by the action of methanol and ethanol respectively on PtCl2·2PCl3. 2. By means of an exchange reaction with potassium iodide, PtCl2·2P(OC2H5)3 and PtCl2-2P(OC3H7-i)3 have been converted into the corresponding iodides. 3. By the action of thiourea on the complexes PtCl2-2P(OR)3 (where R = CH3; C2H5; C3H7-i), crystalline compounds have been prepared which correspond in their analyses to, i.e. p.42 where R =CH3; C2H5 and C3H7-i. © 1953 Consultants Bureau.
