반응 단계
Chlorobenzene (0.4 mol) and aluminium chloride (0.5 mol) in carbon disulphide (30 ml) were stirred at 50°-60°. Fumaryl chloride (0.2 mol) was added dropwise at a brisk rate over 30 minutes and refluxing was continued for a further 15 minutes. The residue was poured into crushed ice (1 kg) and concentrated hydrochloric acid (15.0 ml). The semi-solid was filtered off, washed with ether and ethanol, and recrystallised from ethyl acetate/ethanol to give pale yellow needles of di-(p-chlorobenzoyl) ethylene m.p. 175°-176°. Analysis:
