Abstract
Process for the preparation of alpha, beta-unsaturated ketones, based on substituted cyclohexadienes, characterized in that 1-methyl-cyclohexadienes with substitution sites, optionally in position 3 or 4 according to constitution i, or 1-methylene-cyclohexenes with substitution sites, optionally in position 4 and 3 according to constitution ii, are first transformed with halohydrazide, preferably at temperatures around 0º, optionally in the presence of indifferent solvents with cyclic allyl halides and because these are preferably converted at temperatures of below 0º with solution of aqueous bichromate by oxidation of the alpha, beta-unsaturated ketones.
