The electroreduction of CF3Br in DMF containing aldehydes or ketones, using a sacrificial zinc anode, affords the corresponding trifluoromethyl alcohols together with the unreactive organozinc species CF3ZnBr and (CF3)2Zn. The alcohols are obtained with good yields from aldehydes. With ketones the organozinc species are formed preferentially to the alcohols, but the addition of tetramethylethylene-diamine
