Treatment of cyclic ketones, e.g. 4, with tungsten hexachloride (WCl 6) provided good yields of vinyl chlorides, e.g. 5, and/or gem-dichlorides. A trans-diequatorial dichloride 9 was prepared by treatment of the corresponding epoxide 8 with WCl

Paragraph 0048-0050, (2019/12/25)
The invention discloses a preparation method of a heteroatom-containing cyclohexene halide, belonging to the field of synthesis of fine chemical intermediates. According to the preparation method, cyclohexanone containing heteroatoms is used as a raw material, and gem-dihalide or alkenyl halide is mainly generated in a halogenating reagent; and after an additive is added into organic alkali, and hydrogen halide is removed to generate cyclohexene halide containing heteroatoms. The method is simple in process; the operation of purifying a mixture in traditional methods is avoided; and a productis fully utilized. Under close-to-elimination condition of gem-dibromide, an additive is added to overcome the problem of difficulties in gem-dichloride elimination is by adding, and the purpose of controlling regioselectivity is achieved through steric hindrance of different alkalis.
