Abstract
The reactions of the product of cyclodehydration of (2-pyridylthio)acetic acid, viz., 2-[(1-methyl-2-pyridylthio)acetyl]thiazolo[3,2-a]pyridinium 3-oxide, were investigated. It is shown that its quaternary salt at the pyridine nitrogen atom in the presence of triethylamine acts as a nucleophile (by reactions at the methylene group with benzothiazolium and quinolinium sulfonatobetaines) and as an electrophile (by reaction with N-phenylrhodanine) with cleavage of both sulfide sulfur bonds with the simultaneous formation of a disulfide.
