The Addition of bromine to phenylpropiolic acid

Abstract

Considerable attention has recently been focused upon the nature of the kinetics of halogen additions to unsaturated compounds Probably the first noteworthy contribution towards the establishment of the mechanics of additions to ethylenic compounds was set forth by Lowry (1), when he gave an explanation of the electron distribution and consequent polarity associated with the unsaturated ethylenic system, which was followed by a further suggestion by Francis (2), relating to bromine addition in aqueous solution. Later, the examination of halogen addition to the double bondwas made by Ingold and Ingold (3) in terms of electronic theory, and the present theory based upon their investigation has since had substantial confirmation.
