The halogen—metal exchange between 2,7-dibromonaphthalene or 2,7-dibromoanthracene and n-C4H9Li has been investigated. For exchange of only one bromine atom the best yields are achieved in diethyl ether at 20° C, while the exchange of both bromine atoms gives satisfactory yields in tetrahydrofuran at −35° C.
研究了2,7-二溴萘或2,7-二溴蒽与nC 4 H 9 Li之间的卤素金属交换。对于仅交换一个溴原子,在20°C的乙醚中可获得最佳收率,而两个溴原子的交换在-35°C的四氢呋喃中均提供令人满意的收率。
