4,6-Diphenyl-1,2-dihydropyrimidine was prepared by LiAlH4 reduction of 4,6-diphenylpyrimidin-2(1H)-one or 4,6-diphenylpyrimidine.Using 1H and 13C NMR, it was shown that in CDCl3 the product exists in tautomeric equilibrium with 4,6-diphenyl-2,5-dihydropyr

A series of 1,2- and 2,5-dihydropyrimidines was synthesized by LiAlH4 reduction of the corresponding pyrimidines.It was demonstrated that these compounds undergo imine-enamine tautomerism.The ratio as well as the stability of imine (2,5) or enamine (1,2)
