THE REACTION OF NITRILES WITH O,O-DIALKYL-DITHIOPHOSPHORIC ACIDS
Nitriles react with dialkyldithiophosphoric acids 2a-c to give a mixture of corresponding thioamides and O,O-dialkyl-N-thioacetyl-phosphoroamidothioates 3a-e.The structure of compounds 3 are elucidated chemically and from electronic spectra.The yield of thioamides are improved from the reaction of nitriles with compound 2b in presence of water.Mechanistic consideration on the formation of the products are discussed.

STUDIES ON ORGANOPHOSPHORUS COMPOUNDS PART 55 THE TRANSFORMATION OF NITRILES TO THIOAMIDES WITH O,O-DIALKYLDITHIOPHOSPHORIC ACID
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.
