实验步骤: Nitric acid (25 g.) was added during three hours to a mixture of (2,2-dichlorocyclopropyl)benzene (45 g.), water (13 g.), acetic acid (40 g.) and concentrated sulfuric acid (177 g.) with cooling (to 3-5° C.). The resulting mixture was quenched in a mixture of ice (400 g.) and chloroform (200 g.). The layers were separated and the aqueous layer was washed with chloroform (100 g.). The chloroform layers were combined and washed with aqueous sodium carbonate (5%, 300 ml.). The sodium carbonate layer was backwashed with chloroform (75 g.). The combined chloroform extracts were dried, fitered and concentrated, affording p-(2,2-dichlorocyclopropyl)nitrobenzene mixed with the ortho isomer (57 g.). The resulting mixture was quenched in a mixture of ice (400 g.) and chloroform (200 g.) The layers were separated the aqueous layer was washed with chloroform (100 g.) washed with aqueous sodium carbonate (5%, 300 ml.) The combined chloroform extracts were dried concentrated

实验步骤: 312 g of styrene are reacted with chloroform as described in (I). Afer 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. Afer a post-reaction time of 5 hours, fractional distillation
