Reaction of Acetaldehyde and Malononitrile. 2,2,4,4-Tetracyano-3,5-dimethylcyclohexylmalononitrile

Abstract

The condensation of acetaldehyde and malononitrile is reported to yield 1,1,3,3-tetracyano-2,4-dimethylcyclobutane. The n.m.r. spectrum of this material and several of its derivatives, however, was found to best fit the title compound. A reaction scheme for the formation of the title compound is suggested.
