Dihydration (covalent) of condensed pyrazine heterocycles
Abstract
Proton magnetic resonance measurements show that the cations of 1,4,5- and 1,4,6-triazanaphthalene, 1,4,5,8-tetra-azanaphthalene, and five of their derivatives add two molecules of water reversibly, across the 1,2 and 3,4 C
N bonds.
