The present account deals with the synthesis, stereochemistry and biological properties of coordinatively saturated difluoroboron(III) compounds.The ligands used during the present investigations were prepared by the condensation of , , , and with 2-mercapto-aniline.The unimolar reactions between borontrifluoride-acetic acid and these ligands have produced BF2(NS) type of biologically active complexes.The quantitative and spectral analyses comprising u.v., i.r. and n.m.r. (1H, 11B, 13C and 19F) helped in establishing the structures of the resulting complexes.In the quest for better fungicides and bactericides, studies were conducted to assess the growth inhibiting potential of the synthesized complexes against various fungal and bacterial strains.The studies demonstrate that the concentration reached levels which are sufficient to inhibit and kill the pathogens.

Highly efficient synthesis of benzofused heteroaromatic compounds via aerobic oxidation catalyzed by cyanide anion has been developed. The Schiff bases derived from 2-aminophenol and aldehydes provided the corresponding benzoxazoles in high yields in the presence of a catalytic amount of cyanide in an open flask under ambient conditions without the use of any external metal co-oxidants and bases. Furthermore, we have developed a catalytic sequential one-step protocol for the synthesis of benzoxazoles by adding a catalytic amount of NaCN to Schiff bases generated in situ from 2-aminophenol and aldehydes without the isolation of imine intermediates. This one-pot protocol was further extended to the synthesis of benzothiazoles from 2-aminothiophenol and aldehydes. A variety of aldehydes could be applied to this sequential one-pot protocol and the desired benzofused azole products were obtained in high yields.

Five heterocyclic benzothiazoline and -thiazole analogs have been synthesized and characterized by 1H NMR and IR spectroscopy. The analogs fall into two different classes, (a) those which contain one benzothiazoline group adjacent to the hetero
