1,2-Addition of α,α,α-trichlorotoluene to ketones via a Mg Barbier reaction in DMF: New route to cycloalk-1-en-1-yl and alk-1-en-1-yl phenyl ketones

The reductive cyclocondensation of α,α,α-trichlorotoluene to enolisable ketones enables the preparation of (cyclo)alken-1-en-1-yl phenyl ketones via the formation of an intermediate chlorooxirane. Copyright Taylor & Francis Group, LLC.

REACTIONS OF POLYHALO FUNCTIONAL COMPOUNDS WITH METALS AND ELECTROPHILIC REAGENTS. XVI. CHEMICAL BEHAVIOR OF α,α-DIBROMO KETONES IN THE REFORMATSKII REACTION

Geminal α,α-dibromo ketones react with zinc and carbonyl compounds.Depending on the structures of the reactants, the nature of the solvent, and the reaction conditions, α,β-unsaturated ketones, α,β-epoxy ketones, or α-alkyl-β-diketones or their mixtures are formed.

Cathodic Addition of Benzylidyne Trichloride to Ketones and Aldehydes

Ketones are converted to homologated enones 7a-g in good yields by cathodic addition of benzylidyne trichloride (1d).As intermediates α-Chlorooxiranes 6 are assumed, which rearrange via α-keto carbenium ions 9 to enones.The intermediacy of 9 is supported by the addition of 1d to norcamphor, where the products indicate equilibrating norbornyl cations as intermediates. α,β-Unsaturated ketones lead depending on steric shielding of the double bond to the cyclopropane 23 as 1,4-adduct or the enone 26 as 1,2-adduct.With aldehydes and 1d, α-chloro or βhydroxy ketones, the conversion products of 2-chlorooxiranes, are obtained.
