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