- The lithio-derivative can also be acylated with esters, lactones, amides or nitriles. In these applications, benzothiazole is claimed to be superior to the better known 1,3-dithiane as a formyl anion synthon.

- Reaction of the lithio-derivative at low temperatures with PCl3 gives, as the major product, 2,2'-bibenzothiazole instead of the expected tertiary phosphine: Heterocycles, 30, 347 (1990). POCl3 or SOCl2 also promote the symmetrical coupling reaction: Heteroatom. Chem., 5, 409 (1994).

- n-BuLi gives the 2-lithio-derivative, stable below -50o, which behaves as a formyl anion equivalent, reacting with aldehydes and ketones. The derived alcohols have been transformed into various useful products, e.g. ɑ-hydroxy ketones: Tetrahedron Lett., 5, 9, 13, (1978); Bull. Chem. Soc. Jpn., 61, 3637 (1988):
