Abstract

Amines were treated with the N-phosphonium salts of pyridine prepared by the oxidation of the phosphorous acid and its esters with mercuric chloride in pyridine; they yielded the corresponding amides in good yields upon acidolysis with carboxylic acids, together with metallic mercury in a nearly quantitative yield. The reaction was studied using phosphorous acid and its several esters, and was presumed to proceed via the activation of amines by ...
