2-Substituted 1,3-Benzoxathiolium Tetrafluoroborates as Useful Acylating Agents of Electron-Rich Aromatic and Heteroaromatic Compounds

2-Substituted 1,3-benzoxathiolium tetrafluoroborates were used for the two-step acylation of electron-rich aromatic and heteroaromatic compounds: 1,3-dimethoxybenzene, 1,3,5-trimethoxybenzene, pyrrole and indoles.In most of the cases intermediate 2,2-disubstituted 1,3-benzoxathioles were obtained in good to high yields (55-100percent) and subsequent hydrolysis of these with mercury(II) oxide and aqueous tetrafluoroboric acid (35percent) in tetrahydrofuran afforded the corresponding ketones in almost quantitative yields.
