A polyvinylpolypyrrolidone supported triflic acid was shown to be useful as a recyclable heterogeneous catalyst for the rapid and efficient synthesis of quinoxaline derivatives in good-to-excellent yields.The catalyst is easily prepared,air-stable,reusable,and easily removed from the reaction mixtures.
