In contrast to alkyl esters of carboxylic acids, 3-acyloxysulfolanes on reaction with nucleophilic reagents readily split out a carboxylic acid to give 2-sulfolene, which then reacts with compounds containing a labile hydrogen atom. On the basis of d

The behavior of various sulfolenyl and sulfolanyl sulfonates in the Friedel-Crafts reaction was studied. The sulfolane ring undergoes both arylation and halogenation. The ratio of reaction products depends on the nature of the starting sulfonate.

β-Alkoxysulfolanes in the presence of equimolar amounts of sodium ethoxide react with malonic acid derivatives in which the hydrogen atom of the methylene group is activated by CN, COOR, CONH2, and SO2R substituents to give compounds that are identi

The reaction of arylhydrazones of 4-arylthiosemicarbazides of arylsulfonylglyoxylic acid with ω-bromoacetophenone has given arylhydrazones of N-(3-aryl-4-phenyl-2-thiazolinylidene)hydrazides of arylsulfonylglyoxylic acids. The reaction of ethyl p-to
