General description
Pyrazine is a 1,4-diazine and an electron-deficient N-heteroarene found in several natural products, APIs, agrochemicals, and functional materials.
Application
Pyrazine can be used:
- As a bridging ligand in the synthesis of Cu(II) linear chain coordination complexes.
- To prepare Cu(I) derived coordination polymers, which are used in the synthesis of metal-organic frameworks (MOFs).

A one-step transformation of heterocyclic N-oxides to 2-alkyl-, aryl-, and alkenyl-substituted N-heterocycles is described. The success of this broad-scope methodology hinges on the combination of copper catalysis and activation by lithium fluoride or magnesium chloride. The utility of this method
