Abstract

lier paper'IV was prepared by the action of an alcoholic solution of anhydrous potassium acetate on the dibromide. Two other methods of preparation are herein described. Method A is particularly significant since a, 8-dibromo ketones are not generally pyrolyzed to give a- bromo un-saturated ketones as the chief product. By the Plyrolysis of the Dibromide.-Five grams of o-chlorobenzalacetophcnone dibro: iiide was heated for one and one-half hour.; ...
