Reaction of tetracyanoethylene with alpha,beta-unsaturated ketones

Synthesis and Chemistry of simple tetracyanoalkanes is well studied. We performed tetracyanoethylation of unsaturated ketones with an active double bond in alpha-position. The reaction of tetracyanoethylene with alpha,beta-unsaturated ketones may result in four probable products depending on the character of substituents.

A new route to 1-substituted 2,2,3,3-tetracyanocyclopropanes

2,2,3,3-Tetracyanocyclorpropyl ketones were prepared by reaction of tetracyanoethylene with a-chloro ketones.
