REACTIVITIES OF PHOSPHORUS DITHIOACIDS AND S-TRIMETHYLSILYL DITHIOPHOSPHATES IN REACTIONS WITH p-QUIONONES

Reactions between phosphorus dithioacids and S-trimethylsilyl dithiophosphates and p-quinones yield S-2-hydroxy(trimethylsiloxy)aryl dithiophosphates which are further capable of isomerizing to the respective O-2-mercaptoaryl thiophosphates.On the basis of investigations of the kinetics of dithiophosphate addition to p-benzoquinone in various solvents and kinetic iosotopic effect, some conclusions have been reached concerning the mechanism of the reaction.Investigation of the S --> O isomerization of S-aryldithiophosphates suggest that the reaction involves formation of intermediates with hydrothiophosphorane structure.In the case of S- 2,4-bis(trimethylsiloxy)phenyl dithiophosphates, the migration of the thiophosphoryl group has been found to be reversible.Isomerization of this kind has also been found to occur in products of addition of dithiophosphates to p-naphthoquinone and N-benzenesulfonyl-p-benzoquinoneimine.
