Unusual direction of the radical reaction of esters with ethylenic compounds

Abstract: 1. A study was made of the addition reaction, initiated by peroxides, of diethyl malonate, dimethyl succinate and ethyl monochloroacetate to the polyhaloolefins — to hexafluoropropylene, trichloroethylene and tetrachloroethylene. 2. The reaction proceeds by an anomalous direction: the α-carbon atom of the alcohol portion of the ester molecule takes part either exclusively or predominantly in the formation of the new carbon — carbon bond of the adducts. 3. The reaction of esters with trichloro- and tetrachloroethylene is accompanied by the elimination of hydrogen chloride and leads to the respective formation of either the 1-(dichlorovinyl) or 1-(trichlorovinyl) derivatives of alkyl esters of carboxylic acids.
