    Abstract: Aromatic substrates such as fluorobenzene can be selectively brominated in high yield and conversion in short reaction periods by reacting the substrate with a brominating agent in a liquid reaction medium and in the presence of a catalyst composition formed by including in the medium a combination of (i) a shape selective HY or HM or zeolite catalyst, and (ii) at least one Lewis acid in a ratio of from 0.005 to 0.5 part by weight of (ii) per part by weight of (i). The bromination is performed at one or more temperatures in the range of 30 to 70° C., and the amount of the zeolite is no more than about 10 grams per mole of aromatic substrate.

    Abstract: In producing (.+-.)-2-(6-methoxy-2-naphthyl)propionic acid or precursor thereof from 2-bromo-6-methoxynaphthalene, use is made of 2-bromo-6-methoxynaphthalene formed by (a) methylating 6-bromo-2-naphthol with methyl chloride in a solvent comprising one or more compounds, RZ, where R is a hydrogen atom or an alkyl group, and Z is --OH or --CN provided that if Z is --CN, R is alkyl, and in the presence of a strong base; and (b) recovering and purifying 2-bromo-6-methoxynaphthalene so formed. Preferably, the 6-bromo-2-naphthol is formed by (1) reacting 1,6-dibromo-2-naphthol with hydrogen, in a solvent comprising (a) organic halide in which the halogen has an atomic number of 35 or less or (b) a mixture of water and such organic halide, and in the presence of catalytically effective amounts of (i) a tungsten carbide-based catalyst, and (ii) phase transfer catalyst; and (2) separating 6-bromo-2-naphthol from the organic halide solvent so that the 6-bromo-2-naphthol is substantially free of halogen-containing impurities before use in the above methylation reaction. This technology makes possible reductions in quantities of co-products formed, eliminates need for use of excess iron and/or dimethyl sulfate as reaction components, and makes possible improvements in plant operating efficiency. Precursors of (.+-.)-2-(6-methoxy-2-naphthyl)propionic acid formed from such 2-bromo-6-methoxynaphthalene are Grignard reagent of 2-bromo-6-methoxynaphthalene, bis(6-methoxy-2-naphthyl)zinc, 6-methoxy-2-naphthylzinc halide, 6-methoxy-2-naphthyllithium, 6-methoxy-2-naphthylcopper(I), bis(6-methoxy-2-naphthyl)cadmium, 6-methoxy-2-naphthylcadmium halide, and 6-methoxy-2-vinylnaphthalene.
