Abstract

5.88 (s,2 H), 7.30-7.80 (m, 8 H). Anal. Calcd for CaHaN2SzBzF8: C, 49.8; H, 4.2; N, 4.8. Found: C, 50.1; H, 4.0; N, 5.2. Preparation of Bis(benzothiazo1ine) Derivative 12. To a suspension of dication 11 (578 mg, 1.0 mmol) in acetonitrile (15 mL) was added an excess of triethylamine. The mixture was stirred at room temperature for 12 h. Evaporation of the solvent yielded a brown solid which was purified by column chroma- tography on alumina with ...
