Hasanein, Ahmed A. published the artcileDFT calculations of amine-imine tautomerism in some pyrimidine derivatives and their 1:1 and 1:2 complexes with water, Category: pyrimidines, the publication is International Journal of Quantum Chemistry (2011), 111(15), 3993-4010, database is CAplus.
Amine-Imine tautomerization in 2-amino-pyrimidine (I), 2-amino-4,6-dichloropyrimidine (II), 2-amino-4,6-dimethylpyrimidine (III), and 2-amino-4,6-dimethoxypyrimidine (IV) and their 1:1 and 1:2 H-bonded complexes with water have been studied using the B3LYP/6-31++G** method. Optimum mol. geometries, electronic properties, and energetics of these systems have been discussed. © 2011 Wiley Periodicals, Inc. Int J Quantum Chem, 2011.
