Bromination Of Cinnamic Acid. Since this attack can occur both at positions 2 and 3, and because the reaction proceeds stereospecifically with inversion, both bromonium ions will give rise to mutually identical pairs of enantiomeric. You will use your textbook and your knowledge of organic chemistry to predict the stereochemical outcome of the product.
Bromination And Elimination
Web the bromination of cinnamic acid leads to two intermediate enantiomeric cyclic bromonium ions which are subsequently attacked by a nucleophilic bromide ion. Deuteriation of bromobenzoic acids in the presence of homogeneous platinum catalyst. This is important in the determination of dibromide’s stereochemical structure, as a. Since this attack can occur both at positions 2 and 3, and because the reaction proceeds stereospecifically with inversion, both bromonium ions will give rise to mutually identical pairs of enantiomeric. Back in your hood, securely support the separatory funnel over the flask. You will then perform the reaction and use the melting point of the product to test your hypothesis. Attach a heating mantle and variac and heat the mixture to a gentle reflux. Obtain 4.0 ml of a 1.0 m solution of bromine in methylene chloride in the addition funnel. Web weigh your cinnamic acid unknown sample into a 50 ml erlenmeyer flask and add 6.0 ml of glacial acetic acid. Take your separatory funnel to the hood, put 8.2 ml of a 1.25 m solution of bromine in acetic acid into the funnel and stopper it immediately.
