The structures and the reactivities of the title vinylogous sulphonamides are compared with those of the corresponding vinylogous amides derived from cyclohexane-1,3-dione. Their behaviour on alkylation, acylation, and addition-substitution has been studied. Isolation of some of the products can be explained in terms of the existence of a tautomeric equilibrium in the parent systems.
将标题乙烯基磺酰胺的结构和反应性与衍生自环己烷-1,3-二酮的相应乙烯基酰胺的结构和反应性进行了比较。研究了它们在烷基化,酰化和加成取代方面的行为。某些产物的分离可以通过母体系统中互变异构平衡的存在来解释。
