Abstract

Abstract: Rate constants are reported for the buffer-independent decay of ten (E)- arylmethanediazoates in aqueous media at 25 OC, ionic strength 1 M (NaClOd), 4% 2- propanol, in the region of pH 4-12. The rate constants are proportional to hydrogen ion concentration at high pH and become pH independent in the low-pH region. Varying concentrations of oxyanion, amine, and hydrazine buffers over the range 0.05-0.2 M ...
