Abstract

Abstract The halogen—metal exchange between 2, 7-dibromonaphthalene or 2, 7- dibromoanthracene and nC 4 H 9 Li 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.
