Expanding applications of zeolite imidazolate frameworks in catalysis: synthesis of quinazolines using ZIF-67 as an efficient heterogeneous catalyst

A cobalt zeolite imidazolate framework (ZIF-67) was successfully synthesized and characterized, then used as an efficient catalyst in a reaction to form quinazoline products. ZIF-67 could be recovered and reused several times without significant degradation in its activity.
