The reaction of 8,16-bis(bromomethyl) [2.2]metacyclophanes (2) with phenyl lithium in ethyl ether afforded the unexpected spiro compounds 3. It was also found that 8,16-unsymmetrically disubstituted [2.2]metacyclophanes 9 such as 8-methyl-16-halomethyl- and 8-methyl-16-methoxy derivatives were easily prepared from 3.
8,16-双(溴甲基) [2.2] 间环芳烃 (2) 与苯基锂在乙醚中的反应得到了意想不到的螺环化合物 3。还发现 8,16-不对称双取代的 [2.2] 间环芳烃 9 如 8 -甲基-16-卤甲基-和8-甲基-16-甲氧基衍生物很容易从3制备。
