The addition of thiols and amines to 3(2H)thiophenone 1,1-dioxide takes place with extrusion of sulfur dioxide,furnishing in high yields the corresponding vinyl sulfides and enamines. Addition of dithiols afforded the corresponding thioacetals. The rates of the the Michael addition and the extrusion reaction are strongly influenced by the solvent employed. In ethanol, sulfur dioxide extrusion took
通过挤出二氧化硫将硫醇和胺加到3(2H)噻吩1,1-二氧化物中,以高收率提供相应的乙烯基硫化物和烯胺。加入二硫醇得到相应的硫缩醛。迈克尔加成反应的速率和挤出反应受到所用溶剂的强烈影响。在乙醇中,即使在室温下也发生二氧化硫挤出。
