The bromination of allyl acetate and allyl benzoate in carbon tetrachloride and chloroform

Abstract

The mechanism of the addition of halogens to the ethylene link has been investigated by various workers. Bromine addition in dissociating solvents involves attack by the positively polarised bromine atom on the negative carbon atom in the ethylenic system. (Robertson, Clare, McNaught and Paul 1.) The resulting positive charge on the other carbon atom is then neutralised by the negative bromine ion. The same authors have shown that bromine adds on by a termolecular mechanism. Chlorine on the other hand adds on by a bimolecular mechanism. (White and Robertson, 2.)
