Cinnamic acid reaction
WebBromination of trans-cinnamic acid The procedure of the reaction starts with the dissolution of 2.2 g of trans-cinnamic acid (MW = 148 g/mol), which corresponds to 1.49x 10-2 mol, and 5.3 g of pyridinium tribromide (MW = 320 g/mol), which corresponds to 1.67x10-2 mol, in 18 mL of glacial (i.e. concentrated) acetic acid as the reaction solvent. WebPerkin's reaction: When benzaldehyde is heated with acetic anhydride in the presence of sodium acetate, it forms cinnamic acid.
