<i>ortho</i>-Disubstituted<i>F</i>-Benzenes. III. Preparation of (<i>F</i>-Benzo)heterocyclic Compounds from<i>F</i>-Benzoic Acid and<i>F</i>-Phenol, and the Reactions of Some Intermediary<i>F</i>-Benzoyl- and<i>F</i>-Phenoxy Compounds
With the intention of achieving the selective ortho-substitution of F-benzoic acid and F-phenol via intramolecular nucleophilic cyclization, preparation of some requisite precursory F-benzoyl- and F-phenoxy compounds and their nucleophilic cyclization reactions were examined. 1,2-(F-Benz)isoxazol-3(2H)-one, 2-(p-tolyl)-1,2-(F-benz)isoxazol-3(2H)-one, 1,3-dimethyl(F-benzo)pyrimidine-2,4(1H,3H)-dione
