In the past, most of the reaction conditions employed toxic halogenated solvents, and have required addition of molecular bromine (br 2), which is also toxic. These observations are rationalised by means of hammett and. The traditional reaction uses a bromine solution in.
In both cases, the nucleophilic double bond undergoes an electrophilic addition reaction by the bromine reagent. Use perspective formulas to illustrate your answer. Stilbene bromination reactions that incorporate halogens into compounds are widely used in organic chemistry.
You will brominate stilbene by using br 2 generated by oxidizing hydrobromic acid with hydrogen peroxide. The reaction is stereospecific through an anti addition to the double bond. These observations are rationalised by means of hammett and taft parameters.
