The reaction of arylmethylenepinacolones, chalcones and 2-arylmethylene-1-tetralones with P4S10 in the presence of triethylamine gave the title compounds, from which 2-thioxo-1,2-thiaphospholes (phosphathiophenes) were generated by the thermolysis and reacted with acrylonitrile to give [4+2]cyclo-adducts.
在三乙胺的存在下,芳基亚甲基松果酮,查耳酮和2-芳基亚甲基-1-四氢萘酮与P 4 S 10的反应得到标题化合物,通过热解从中生成2-硫代-1,2-噻吩(磷噻吩)并反应用丙烯腈得到[4 + 2]环加合物。
