Paragraph 0032-0034, (2018/04/03)
The invention provides a preparation method of 1-(4-chlorphenyl)-2-cyclopropyl-1-actone. The 1-(4-chlorphenyl)-2-cyclopropyl-1-actone is prepared by reacting a compound of a structure in Formula (II)with p-chlorobenzaldehyde. The reaction raw material is low in price and easy to obtain, and the production cost is greatly reduced; the synthetic route is short and simple in technique; the raw material preparation and synthesis of the 1-(4-chlorphenyl)-2-cyclopropyl-1-actone are free from waste water, thus the risk to people and environment is reduced; and the green and environment-friendly chemical industry development requirement is met.

Bicyclo[3.2.0]hept-2-enes undergo thermal rearrangement to norbornenes via diradical transition structures. The synthesis of exo-7-cyclopropylbicyclo[3.2. 0]hept-2-ene has been achieved by cycloaddition of cyclopentadiene and cyclopropylketene, generated by treatment of cyclopropylacetyl chloride with triethylamine. A comparison of the cyclopropyl substituent effect with that of other C7 substituents provides experimental evidence of an electron-donating conjugative effect on the transient diradical transition structure in the thermal reaction of exo-7-cyclopropylbicyclo[3.2.0]hept-2-ene.
