Application

2-Chloroquinoxaline (QCI) was used to study the effect of solvent on hydrolysis of QCI in aqueous–organic solvent mixtures with acetonitrile and dimethylesulphoxide. It was used in the synthesis of 2-(3-butynyl-2-methyl-2-ol) quinoxaline.It was used as reagent in the synthesis of chloroquinoxaline sulfamide.

A model system for the molybdenum cofactor has been developed that illustrates the noninnocent behavior of an N-heterocycle appended to a dithiolene chelate on molybdenum. The pyranopterin of the molybdenum cofactor is modeled by a quinoxalyldithiolene ligand (S(2)BMOQO) formed from
