Reaction Steps
200 parts of 98 per cent strength by weight aqueous phosphoric acid containing 0.9 part of phenylthiourea are irradiated for 10 minutes at 25° with ultraviolet light (mercury vapor lamp, with 15 watt hours per kilogram of halogenostyrene III) whilst passing 2,000 parts of air through the mixture. 70 parts of phosphorus oxychloride are added followed by a mixture of 120 arts of p-chlorostyrene and 97 parts of o-chloroethylbenzene added over 3 hours. Distillation of the organic phase gives 97 parts (= 80.7% of theory) of 1-methyl-3-(p-chlorophenyl)-5-chloroindan of b.p. 148° to 156° C (0.15 mm).
