Aqua mediated SnO۲ nanoparticles: A recyclable and benign catalyst for the synthesis of Quinoxalines

An efficient and mild synthesis of quinoxalines in cludingcyclo-condensation of ۱, ۲-phenylenediamine and ۱, ۲-diketonesin the presence of۱mol% catalytic amount of SnO۲ nanoparticles (۱ mol%) in water at room temperature is established. On the whole, this study introduced at this point is substantial in terms of using water as solvent, low reaction time (۵ to ۱۰ minutes), high yields of products (۸۵-۸۸%), reusability of catalyst (three cycles), eco-friendliness, effortlessness of performance and it displays along the line of green chemistry.
