2-(Benzothiazol-2-ylthio)pyridine undergoes lithiation exclusively at the 3-position.The products of reaction with electrophiles of the lithiated species undergo sulfide cleavage to give 3-substituted 2-alkylthiopyridines and/or 3-substituted pyridine-2-thiones.

2-Methylthiobenzothiazole readily gives a methyl group lithio derivative which reacts cleanly with electrophiles.The products are conveniently converted into the corresponding thiols by BuLi at -78 deg C, and this sequence thus provides a convenient two-step mercaptomethylation procedure for alkyl halides, aldehydes, and ketones.

The pathways of the thermal transformations of thiacarbocyanines with various alkyl groups attached to the ring nitrogen atoms of the heteroresidues, of 3,3'-diethylthiacarbocyanine with various anions, and its anhydro base were investigated.The results of the studies are compared with the results of quantum-chemical calculations of the labilities of the bonds in these compounds by the Pariser-Parr-Pople method.
