Dibenzo[a,c]cyclooctene and its 9,10-dihydro and 9,10,11,12-tetrahydro derivatives have been resolved by chromatography and their inversion barriers determined by thermal racemization. The 9,12-dihydro derivative has been studied by 1H NMR bandshape technique.
二苯并[a,c]环辛烯及其9,10-二氢和9,10,11,12-四氢衍生物已通过色谱法分离,其反转化垒通过热消旋法确定。9,1-二氢衍生物已通过1 H NMR能带技术进行了研究。
