The cycloaddition reaction of 3-styryl-1,2-thia phosphole 2-sulfide and 1,5-diphenyl-2,4-pentadiene-1-thione derivatives generated by the thermolysis of 5,6-distyryl-3,8-diaryl-2,9-dithia-1-phosphabicyclo[4.3.0]nona-3,7-diene 1-sulfides have been described. Methacrylonitrile, methyl methacrylate, α-methylstyrene, norbornene, methyl acrylate, styrene, and mehyl vinyl ketone afforded the cycloadducts
3-styryl-1,2-thia phosphole 2-sulfide 与 5,6-distyryl-3,8-diaryl 热解生成的 1,5-diphenyl-2,4-pentadiene-1-thione 衍生物的环加成反应-2,9-dithia-1-phosphabicyclo[4.3.0]nona-3,7-diene 1-sulfides 已有描述。甲基丙烯腈、甲基丙烯酸甲酯、α-甲基苯乙烯、降冰片烯、丙烯酸甲酯、苯乙烯和甲基乙烯基酮提供环加合物或其与硫代磷酰 2-硫化物的重排产物,而偶氮二甲酸二乙酯、乙炔二甲酸二甲酯和 N-(对甲氧基苯基)马来酰亚胺与硫酮生成环加合物。
