摘要：

The readily accessible tetrabromo\2.2\paracyclophane can be dehydrobrominated stepwise four times with potassium tert-butoxide, and the [2.2]paracyclophanines formed thereby are trapped efficiently by furan, diphenylisobenzofuran and tetraphenylcyclopentadienone to give the corresponding cycloadducts. The octaphenyldibenzo[2.2]paracyclophane-1,9-diene 1, which formally consists of two hexaphenylbenzene units, is isolated in particularly high yields (69%).
