α,β-Unsaturated ketones and aldehydes and method of preparation

α,β-Unsaturated ketones and aldehydes, together with a method of preparation thereof which comprises reacting aldehydes and cyclic and acyclic ketones possessing a methyl or methylene group α- to the carbonyl function with N,N-dialkylformamide dialkyl acetal to yield the corresponding enaminoketones and enaminoaldehydes, which enaminoketones and enaminoaldehydes are allowed to react with alkyllithium reagents to yield the corresponding nitrogen-free 2-alkylidene ketones and 2-alkylidene aldehydes.
