Hydrogenolysis of 4,4-dimethyltricyclo[6.3.0.01,7]undecane-2,6-dione with a Pd-C catalyst gave cis-4,4-dimethylbicyclo[6.3.0]undecane-2,6-dione and 8,8-dimethylspiro[4.6]undecane-6,10-dione. The cis isomer has been shown to isomerize almost completely to the trans isomer under acidic and basic conditions.
在Pd-C催化剂作用下,4,4-二甲基三环[6.3.0.01,7]十一烷-2,6-二酮发生氢解反应,生成顺式-4,4-二甲基双环[6.3.0]十一烷-2,6-二酮和8,8-二甲基螺[4.6]十一烷-6,10-二酮。在酸性或碱性条件下,顺式异构体几乎完全转化为反式异构体。
