CHCl(3)-PPh(3), Pd(PPh(3))(4), and Pd(OAc)(2)-dppp are also effective for this reaction. The thiocarbonylation reaction is believed to proceed via an allylpalladium intermediate. The reaction exhibits high regioselectivity, in which the thiophenyl group adds to the less substituteddouble bond of allenes to give beta,gamma-unsaturated thioesters.
