Abstract: The reaction of P(SPh)_{3},
As(SPh)_{3}, and Ph-As(SPh)_{2} with
carboxylic acid anhydrides gives not only the thiol esters RCOSPh, but also the
easily identified triphenyl phosphorotrithioate
O=P(SPh)_{3}, diphenyl disulfide PhSSPh,
and the anion RCOO^{-} in various proportions depending on
the reaction conditions (in solution or neat at 120°C;
in the absence and in the presence of an anhydride activator). The probable
origin of the additional products is discussed.
