Abstract

Six-, five-, four-and three-membered 1, 1-cycloalkanedicarboxylic acid (2a–d) were synthesized by alkaline hydrolysis of the corresponding diesters (1a–d) and the reactions of the formers with SF4 were investigated. 1, 1-Bis (trifluoromethyl) cycloalkanes (3a–d) were the products of the reactions conducted at 120–150° C while at 30° C 1-fluoroformyl-1- (trifluoromethyl) cycloalkanes (4a–d) were exclusively formed. The latter were isolated as ...
