Abstract 1-Fluoro-2-(triethylsilyl) naphthalene (1) and other 1-fluoronaphthalenes bearing a metalation-resistant substituent at the 2-position proved to be totally inert toward base attack. 3-Bromo-1-fluoronaphthalene (6), readily prepared from the 2-bromo isomer 5 by deprotonation-triggered heavy halogen migration, was converted into 3, 3′-dibromo-1, 1′- difluoro-2, 2′-binaphthyl (8) by consecutive treatment with lithium diisopropylamide, ...
