Abstract
Bentonite clay K-10 acts as an efficient reagent for the preparation of quinoxaline derivatives via the condensation of aryl and alkyl 1,2-diamines with α-diketones in ethyl alcohol as a green media at room temperature. Using this method, the title compounds are produced in high to excellent yields and short reaction times.
