Abstract

Monohydrazides of 2-R-4-methyl-4-cyclohexene-1,1-dicarboxylic acids react with trifluoroacetic acid anhydride to give 4-substituted 3,5-dioxopyrazolidines, with phosphorus trichloride to give 4-(2-R-5-chloro-4-methylcyclohexane)-3,5-dioxopyrazolidines, and with acetic anhydride to give 4-(2-R-4-methyl-4-cyclohexene)-3,5-diacetoxypryazoles.
