Six α-sulfinyl phosphorus ylides 6 have been prepared and are found upon flash vacuum pyrolysis at 500 °C to undergo mainly extrusion of Ph3P to give thioesters, presumably by 1,2-oxygen transfer in the initially formed sulfinyl carbenes; for α-arylsulfinyl ylides loss of Ph3PO to give additional products is also observed.
已经制备了六个α-亚硫酰基磷酰化物6,发现它们在500°C的快速真空热解中主要经历Ph 3 P的挤出,从而生成硫酯,大概是通过在最初形成的亚硫酰基羧甲基中进行的1,2-氧转移来实现的。对于α-芳基亚磺酰基基团,还观察到了Ph 3 PO的损失,从而得到了另外的产物。
