## Abstract Methyl‐^14^C iodide of high specific activity was converted to carbon‐14 disulfide in quantitative yield by reaction with phosphorus pentasulfide at 300–325°C. Following literature procedures, N,N′ dicyclohexylcarbo‐^14^C‐diimide was prepared in 54% yield from the carbon‐14 disulfide.
A few years ago, we reported that the alcoholysis of N-BenoyI-N'-phenyldiimide led to the (21 formation of phenyl radicals. Thus this reaction sequence was indeed unique, since it was a heterolysis, which was followed by a homolysis in a polar media.
We wish to report the polarographic study of two series of disubstituted diimides in 70% AQUEOUS ETHANOL WITH O.&N potassium chloride as supporting electrolyte at 30.0°C(\*). See Table I.
