Abstract The lithiation of 4, 4′-dibromooctafluorobiphenyl with n-butyllithium to yield 4, 4′- dilithiooctafluorobiphenyl and 4-lithio-4′-bromooctafluorobiphenyl as a by-product under various conditions is described. It is proposed that thermal decomposition of the lithiated products formed at low temperatures (− 80 to− 90) leads to products originating principally by nucleophilic displacement reactions, while rapid thermal decomposition, after metal- ...
