A process for the production of a 5-7 membered ring cyclic sulfonium salt compound, including a 5-7 membered ring cyclic sulfonium salt compound having a non-nucleophilic anion, is described. Members of the latter group are potentially useful as initiators for cationic polymerizations. The process comprises reacting a 1.4-, 1.5-, or 1.6-diol compound or a 5-7 membered ring cyclic ether compound with a mercapto compound and a strong protonic acid yielding the cyclic sulfonium salt compound. Some compounds described are also novel compounds per se.
生产5-7成员环状磺隆盐化合物的方法,包括具有非亲核阴离子的5-7成员环状磺隆盐化合物的方法。后一组的成员可能作为阳离子聚合的
引发剂有潜在用途。该方法包括将1,4-、1,5-或1,6
-二醇化合物或5-7成员环状醚化合物与巯基化合物和强质子酸反应,生成环状磺隆盐化合物。描述的一些化合物本身也是新颖的化合物。
