実験手順
A mixture of 1,2-diphenyl-1-propene (9.7 g, 50 mmol), N-bromosuccinimide (8.9 g, 50 mmol), dibenzoylperoxide (0.1 g) and tetrachloromethane (50 ml) was heated at reflux for 21 h. The mixture was filtered cold and the solvent evaporated from the filtrate in vacuo to give 13.1 g of 3-bromo-1,2-diphenyl-1-propene as an E/Z isomeric mixture.
