Basolites: a type of Metal Organic Frameworks highly efficient in the one-pot synthesis of quinoxalines from a-hydroxy ketones under aerobic conditions.

Abstract

We report here efficient synthesis of quinoxalines from ophenylendiamine and -hydroxy ketones over commercial Basolites. The concentration and type of acid centres, as CUS sites, together with the porosity of the samples strongly influence the resulting conversion and selectivity. Our results indicate a new reaction route in which tautomerization reactions are also involved.
