The lithiation of 2-chloro, 2-methoxy and 2-pivaloylaminoquinoxaline was studied. In the case of 2-chloro and 2-methoxyquinoxaline the simultaneous formation of dimers could not be avoided. The resulting lithio derivatives were reacted with carbonyl compounds and iodine. Yields in excess of 50% were obtained.
