STUDIES ON ORGANOPHOSPHORUS COMPOUNDS PART 551THE TRANSFORMATION OF NITRILES TO THIOAMIDES WITHO,O-DIALKYLDITHIOPHOSPHORIC ACID

Abstract The reaction between nitriles and O,O-dialkyldithiophosphoric acid (2) under anhydrous conditions produces O,O-diethyl-N-thiobenzoylamidophosphate (5), contrary to literature. When water is present the same reaction gives the corresponding thioamides in reasonable to good yields. Mechanistic considerations and spectral data are presented for the products.
