The Sn(IV)-tetra(4-sulfonatophenyl) porphyrin complexes with antioxidants: Synthesis, structure, properties

Complexes of Sn(IV)-tetra(4-sulfophenyl)porphyrin with antioxidants (methoxydol and ionol) and their precursors (para-cresol and 3-hydroxypyridine) were synthesized. All four complexes were obtained by boiling in aqueous solutions of the p-sulfo substitut

2-SUBSTITUTED 1,3-BENZODITHIOLIUM TETRAFLUOROBORATES AS USEFUL ACYLATING AGENTS OF PYRROLE

A comparative study on the acylation of pyrrole by utilizing 2-substituted 1,3-benzodithiolium tetrafluoroborates instead of 2-substituted 1,3-benzoxathiolium tetrafluoroborates has been accomplished.The use of 2-substituted 1,3-benzodithiolium tetrafluoroborates proved to be more convenient since it gives higher yields of 2-acylpyrroles (58-90percent) and appears of larger applicability for the preparation of symmetrical and unsymmetrical 2,5-diacylpyrroles which were obtained in most cases in quantitative yields.

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.
