(N-Alkylthiocarbamoyl)thionophosphonic Acid Esters

Article abstract of DOI:10.1021/jo00170a018

The title compounds 2 were prepared by the reaction of dialkyl thiophosphites and alkyl isothiocyanates.The diphenyl derivative 2f was also prepared by heating the phosphoryl analogue 1f with P4S10.The spectral differences between the present series 2 and the known phosphoryl series 1 are discussed.Both thiono functions of 2a, 2c, and 2e react with methyl iodide, producing the phosphoryl-containing, synthetically useful zwitterion 7.
