Benzoylnitrene, generated photochemically from benzoyl azide, was inserted stereospecifically into the tertiary C–H bonds of cis- and trans-1,4-dimethylcyclohexanes. The insertion regioselectivities toward the C–H bonds were determined by use of 2-methylbutane and 2,3-dimethylbutane. The insertion proceeds involving the singlet nitrene, but not the triplet, and the photo-Curtius rearrangement takes place independently of the nitrene reaction.
苯甲基氮烯是通过光化学方法从苯甲酰叠氮化物生成的,能够立体专一地插入到顺式和反式-1,4-二甲基环己烷的三级C–H键中。针对C–H键的插入区域选择性是通过使用2-甲基丁烷和2,3-二甲基丁烷来确定的。插入反应涉及单态氮烯,而非三重态,并且光Curtius重排与氮烯反应是独立进行的。
