3,6-DIPHENYL-1,2,4,5-TETRAZINE

3,6-Diphenyl-1,2,4,5-tetrazine may be used in the preparation of dihydropyridazine derivatives, via reaction with cis,cis-cycloocta-1,5-diene.

3,6-Diphenyl-1,2,4,5-tetrazine is an an electron-deficient heteroaromatic azadiene. It participates in inverse electron demand cycloaddition reactions with various dienophiles. It is reported to participate in facile inverse electron demand Diels-Alder reactions with “tunable” reaction rates. The electron transport characteristics of 3,6-diphenyl-1,2,4,5-tetrazine (DPT) single molecular conductor have been studied by density functional theory (DFT) method. Basicity of 3,6-diphenyl-1,2,4,5-tetrazine in aqueous solutions of sulfuric acid (pK_BH+) is -4.8. It undergoes thermal Diels-Alder reaction with C₆₀ to afford monoadducts, possessing a diaryldihydropyridazine function nested atop the fullerene.
