Abstract

1, 1-Difluorocyclopropa[α]naphthalene (1b) is prepared in three steps from 4-bromo-1,2-dihydronaphthalene (7) via carbene addition, benzylic bromination and bidehydrohalogenation. Structural evidence for formation of 1b is based on ¹H- and ¹⁹F-NMR spectroscopy. Compound 1b is stable in solution at −30°. Upon reaction with MeOH/H⁺ it is converted to a 1:2 mixture of 1- and 2-methylnaphthoate (10 and 11, respectively).
