As pharmaceutical intermediates and reagent. In chemical research. The intermediate 2-halo- acetylfurans (chloro or bromo) were obtained by a hazardous procedure involving the treatment of 2-furoylchloride (highly lachrymatory) with diazomethane followed by the decomposition of the intermediate with dry HCl. Three monoprotic tridentate ligands were synthesized by condensation of 2-furoylchloride with anthranilic acid and β-alanine, and 2-acetylpyridine with orthanilic acid.
