Abstract

The reactions of p-nitrophenyl acetate (1) with six 6-substituted 2, 4-diamino-1, 3, 5- triazines,(2a–2f), were kinetically investigated in aqueous DMSO or in water at 30° C. It was found that the reaction rate R could be expressed according to the equation R=(k 0+ k N [2])[1], and that Brönsted-type plots for the k N-reaction give a straight line with a slope (β) of 1.05. The solvent deuterium isotope effect was not observed in this reaction [k N (H)⁄ k N ( ...
