Syntheses of bicyclo[5.3.1]undec-7-en-11-one and bicyclo[5.3.1] undec-7(11)-en-8-one are described and the IR, NMR, and UV properties are compared. The chemical properties of the former are also discussed. Evidence is adduced to show that, as predicted, the latter is the more strained and contains a warped double bond.
描述了双环[5.3.1] undec-7-en-11-one和双环[5.3.1] undec-7(11)-en-8-one的合成,并对IR,NMR和UV特性进行了比较。还讨论了前者的
化学性质。证据表明,正如预料的那样,后者更加紧张,并包含弯曲的双键。
