WebBig Chemical Encyclopedia The photobromination of cinnamic acid This reaction is chosen as an example of still a third class of photochemical reaction -—one in which the quantum yield is considerably greater than unity. It is a typical chain reaction. [Pg.157] Web955. Abstract. The bromination of trans-cinnamic acid was completed to determine dibromide’s stereochemical structure and its mechanism. After the addition of bromine to trans-cinnamic acid, the product was identified by its melting point and infrared spectrum resulting in erythro-2,3-Dibromo-3-phenylpropanoic acid after comparing similar ...
