- SYNTHESIS OF THE NITRILES AND AMIDES OF 1-(ARYLSULFONYL)CYCLOALKANESCARBOXYLIC ACIDS
-
1-Arylsulfonylcycloalkanecarbonitriles were synthesized by the cycloalkylation of arylsulfonylacetonitriles by terminal dihalogenoalkanes under the conditions of phase-transfeer catalysis.Hydrolysis of the products gave 11-arylsulfonylcycloalkanecarboxyli

- ALKYLATION OF ETHYL ARYLSULFONYLACETATES IN CATALYTIC TWO-PHASE SYSTEM
-
It was found that ethyl arylsulfonylacetates could be easily dialkylated or cyclodialkylated in catalytic two-phase systems with concentrated aqueous sodium hydroxide, undergoing no hydrolysis under the reaction conditions.

- Synthesis of 1-Phenylsulfonylcyclopropanecarboxylic Acid Derivatives
-
Ethyl phenylsulfonylacetate was treated with 1,2-dibromoethane in the presence of benzyltriethylammonium chloride and alkali to give 1-phenylsulfonylcyclopropanecarboxylic acid, from which the carbonyl chloride, ester, carboxamide, 1,2-diacylhydrazine, ca
