Abstract: A highly efficient and simple cross-coupling reaction of N-aryl aluminum reagents with Naryl
thiosuccinimides for the synthesis of diarylsulide derivatives using CuCl (20 mol%) as a catalyst
is reported. Under the optimum reaction conditions, the coupling reaction between aryl aluminum
reagents with different substituents and N-aryl thiosuccinimides with different substituents can be
carried out smoothly with 18-94% isolated yields of diarylsulides. The method avoids the use of expensive
transition metals, such as Pd, Ir, or Rh, phosphine ligands, and has the advantages of simple
operation and high reaction efficiency. The structures of all the target compounds are confirmed by
1HNMR and 13CNMR.
