halonaphthols with benzyl/allylbromides is described. Halonaphthols are used as carbon-nucleophiles in dearomatization to form three-dimensional cyclic enones with excellent chemoselectivity, in which etherification of phenolic hydroxyl group could be restrained well by using cesium carbonate as the base. A wide range of cyclic enones is directly prepared from various substituted benzyl/allylbromides and halonaphthols

Room-temperature fluorination of alkoxy-substituted benzene derivatives with caesium fluoroxy-sulphate in the presence of boron trifluoride as catalyst resulted in the formation of ortho- and para-fluro-substituted products, the ratio being dependent on the size of the alkoxy-group, while reactions with 2-alkoxy-naphthalene derivatives resulted in the formation of 1, 1-difluoro-2-oxo-1, 2-dihydronaphthalene
