Triazines, Tetrazines, and Fused Ring Polyaza Systems

Abstract The review covers work published in the calendar year 2018. Novel reaction chemistry and new ring synthetic methods for 1,2,3-triazines, 1,2,4-triazines, 1,3,5-triazines, and tetrazines, are reviewed. Fused polyazapolycyclicaromatics, including purines and pteridines, are discussed.
