ABSTRACT:
A platinum complex useful as a catalyst for converting nitrites into amides comprises a platinum complex of dialkyl phosphine of stoichiometric formula: PtX(R.sub.2 POHOPR.sub.2)(PR.sub.2 OH) where R is an alkyl, alicyclic, chiral, alkylaryl group or substituted alkyl, alicyclic, chiral, alkaryl group or the two R groups attached to one phosphorous atom can form a heterocyclic ring with the phosphorous atom and X is H or a halide. The conversion takes place under reflux conditions to give a high yield of the amide.
