REACTION OF DIISOPROPYLDITHIOPHOSPHORIC ACID WITH BENZONITRILE IN THE PRESENCE OF A THIRD COMPONENT

Reaction in the three component systems nitrile-dithiophosphorus acid-phenol or carboxylic acid proceeds by three routes, all of which include the initial stage of formation of imidoyldithiophosphates.The latter forms stable products by isomerization with 1,3-S->N migration of the thiophosphoryl group and by decomposition under the influence of dithiophosphorus acids, phenol, or carboxylic acid.When aniline or methyl iodide is used as the third component the reaction proceeds by a different route and leads to the formation, respectively, of amidine dithiophosphate salts or a mixture of methylation products.
