In the presence of catalytic amounts of RhH(PPh3)4, 1,2-bis(diphenylphosphino)ethane (dppe), and dimethyl disulfide, cyclic and acyclic α-phenyl ketones reacted with p-cyano-α- methylthioacetophenone giving α-methylthio-α-phenylketones. The activated catalyst containing dimethyl disulfide was effective for the α-methylthiolation reaction of these less reactive substrates.
