developed, involving base-promoted one-pot addition of active methylene compounds to o-iodoarylisothioacyanates and subsequent intramolecular C-S bond formation of the resulting thioamidate anion. The reaction proceeds at room temperature within 1-3 h, affording diversely substituted benzothiazoles in high yields. A possible radical intermediate pathway, via an SRN1 mechanism, has been proposed for intramolecular

The chelate and molecular complexes of 2-(2-benzazolyl, perimidyl)-indandiones-1,3 were synthesized for the first time. The structures of the ligands (tautomeric forms) and complex compounds were determined from the X-ray diffraction, H-1, C-13 NMR, and IR data and the quantum-chemical calculations (RHF SCF in 6-31 G** basis).
