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.

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.

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.
