Photoirradiation of methyl 2′-methyl-2,4′-bithiazole-4-carboxylate () leads predominantly to 4,4′-bithiazole with the formation of a small amount of isothiazole . The ring-selective photorearrangement is interpreted in terms of LUMO bond index.

4-Amino-3-arylisothiazole-5-carboxylateesters are converted to the corresponding desamino, chloro, bromo, and iodo esters by processes involving nonaqueousdiazotization. These related procedures open up the possibility for the conversion of readily available heterocyclic ortho-amino esters and nitriles to related heterocyclic derivatives, which are not easily obtained by alternate routes.
