2-Thio-3-amino-5-arylmethylene-4-imidazolidinones(3) were prepared via the tandem aza-Wittig reaction of vinyliminophosphoranes(1) with carbon disulfide and hydrazines. Then 2-alkylthio-3-amino-5-arylmethylene-4H-imidazolin-4-ones(4) were synthesized by S-alkylation of compound 3. The reaction conditions were discussed, the spectral properties of the synthesized compounds were elucidated, and their structures were confirmed by elemental analysis, IR, ¹H NMR and MS. At room temperature or 60~80℃ the compounds 3a~3d and 4a~4f were obtained in yields of 63%~97% and 53%~76% respectively.
