Chlorovinyl ketones are very important and promising synthons for the preparation of various highly reactive polyfunctionalized compounds, including heterocyclic ones [1]. We previously synthesized alkyl 1, 2-dichlorovinyl ketones from aliphatic carboxylic acid chlorides and 1, 2-dichloroethylene in the presence of aluminum chloride [2]. While continuing studies on the scope of application of the proposed procedure for the ...
