2,2'-Bipyrazine is an organic compound containing two pyridine rings and belongs to a group of multifunctional drugs with anti-inflammatory properties. It has shown promising pharmacological effects on several aspects of inflammation, oxidative stress and tumors.
2,2′-Bipyrazine (bpz) can be used as a ligand to synthesize strongly oxidizing photocatalysts. Ruthenium-based homoleptic tris(bipyrazyl) complex [(Ru(bpz)32+] derived from 2,2′-bipyrazine ligand can be used as an effective photocatalyst for oxidatively induced organic transformations. For instance, [(Ru(bpz)32+] is capable of promoting radical cation mediated Diels–Alder cycloadditions, radical thiol-ene couplings, photooxygenation reactions, and [3+2] cycloaddition reactions.
