A NEW CATALYTIC APPLICATION OF MANGANESE SULFATE IN SYNTHESIS OF SOME HETEROCYCLIC SYSTEMS

Some heterocyclic compounds such as coumarins and quinoxalines in the presence of manganese (II) sulfate monohydrate (MnSO4.H2O) as an inexpensive catalyst have been synthesized. These novel methods are very cheap and they include some advantages, such as excellent yields, use of the safe catalyst and readily available starting materials, and simple work-up procedure.
