Homogeneous H-D exchange of heterocycles and some hydrocarbons with D2O in the presence of pt(II) complexes

The homogeneous isotope exchange of O-, N-, and S-containing heterocyclic compounds and a number of hydrocarbons with D2O in the presence of platinum (II) complexes, viz., potassium tetrachloroplatinite, platinum(II) monochlorodiethylene-triaminepentaacetate, chlorodiethylenediamineplatinum(II), dichloroethylenediamineplatinum(II), dichloroethylenediaminetetraacetatoplatinum(II) and, in the case of hydrocarbons, potassium tetrachloroplatinite, was investigated. The M factors were calculated for the H-D exchange of the hydrocarbons. It was shown that the H-D exchange of benzene has multiple character, whereas it has stepwise character in the case of cyclohexane.
