Stereochemistry of Bromine Addition to an Alkene

Written by Aarti Prabhu Objective: To be able to conduct a reflux reaction, and practice improving recrystallization and mp determination, by the bromination of trans-cinnamic acid to form 2,3-dibromo-3-phenylpropanoic acid, and connect syn and anti addition concepts and stereochemical consequences (erythro & threo) from the addition mechanism. PROCEDURE: Procedure: Observations: Combine 100 mg of trans cinnamic acid in a 4 mL conical vial. 0.1025 g of trans cinnamic acid was added. Add 0.7 mL of dichloromethane and 350 uL of […]
