  环状异羟肟酸衍生物的光化学和热环收缩

  摘要：

  环状异羟肟酸在原位三氟甲磺酸酯化作用后会发生热环收缩。当迁移的碳是亚甲基时，用DBU获得高收率的缩环产物，而用Et 3 N迁移季碳则获得最佳结果。在某些情况下，可以通过改变碱来控制反应的区域化学结果。该新颖的热重排补充了N-甲磺酰氧基内酰胺的类似但光化学重排。

  The present invention relates to the use of halogen-free sulphonic acid esters and/or sulphinic acid esters as flame retardant and/or flame retardant synergists in plastics. The invention furthermore relates to the use of said compounds as radical generators in plastics, particularly in order to increase the molecular weight of the plastics, to branch and/or cross-link the plastics, to reduce the molecular weight of the plastics, to influence the molecular weight distribution of the plastics and to graft unsaturated monomers to the plastics. The present invention furthermore relates to the use of flame-retardant plastic compositions in the electrical or electronics industry, construction industry, transport industry, preferably automobiles, aircraft, trains and ships, for medical applications, for household appliances, vehicle parts, consumer products, packaging, furniture and textiles.
