Abstract

This chapter describes the chemistry of triazines, tetrazines, and fused ring polyaza systems. The complexes of 5,6-diphenyl-3-(2-pyridyl)-1,2,4-triazine have been prepared with copper(II), ruthenium(II), and rhenium(V). A cisplatin type complex of 3-(4'-methylpyridin-2`-yl)-5,6-dimethyl-1,2,4-triazine and platinum(II) is described in the chapter. 5,6-diphenyl-1,2,4-triazine-3-one has been obtained in the form of a stable rhenium(V) complex by the reaction of benzil bis(semicarbazone) with common rhenium(V) nitrido complexes. Methodology for the synthesis of pyridines via inverse electron demand Diels–Alder (D–A) reaction of 1,2,4-triazines has been successfully used to search for new ligands and materials. The synthesis of pyridine and bipyridine derivatives of m-carborane by D–A reaction of 1,2,4- triazines 1 with 9-allyl-m-carborane and their structural characterization and photophysical properties are described in the chapter.
