Irradiation of mixtures of chloroacetone and cyclohexene with light (λ > 280 mµ) gave acetone, chlorocyclohexane, bicyclohex-2-enyl (II), cyclohexylacetone, and cyclohex-2-enylacetone. Similar mixtures of saturated and unsaturated ketonic adducts were derived from the illumination of mixtures of chloroacetone and pent-1-ene p-menth-1-ene, the trimethylstyrene (XVIII) and 2,3-dihydropyran. 2-Chlorocyclohexanone
用光(λ> 280 m µ)照射氯丙酮和环己烯的混合物,得到丙酮,氯环己烷,双环己-2-烯基(Ⅱ),环己基丙酮和环己-2-烯基丙酮。相似的饱和酮和不饱和酮加合物混合物是通过对氯丙酮和戊-1-烯对-薄荷-1-烯,三甲基苯乙烯(XVIII)和2,3-二氢吡喃的混合物进行照明得到的。2-氯环己酮和溴丙酮的行为相似,但环己烯中的碘丙酮主要产生反式-2-碘环己基丙酮和碘环己烯。研究了稀释以及向其中一些系统中添加四氯化碳和硫醇的影响。
