Procedure

312 g of styrene are reacted with chloroform as described in (I). After a post-reaction time of 5 hours, fractional distillation gives 45 g of styrene and 444 g of 2,2-dichloro-1-phenyl-cyclopropane of boiling point 103°-104° C./11 mm. This corresponds to 79.2% of theory or 93% based on styrene converted.
