On the Reaction between 1-Aza-1,3-dienes and Push-Pull Olefins of the Acyloxymethylidene-malononitrile Type
摘要:
The reaction between push-pull olefins of the acyloxymethyiidene-malononitrile type and alpha,beta-unsaturated hydrazones affords selectively 5-alkyl-2-cyano-6-(N',N'-dimethylhydrazono)-hexa-2,4-dienenitriles. No [4+2]-cycloaddition products were detected. The structure elucidation of the obtained compounds and possible reaction mechanisms are discussed.
