Abstract

Ketones undergo oxygen exchange with water at a rate which depends on both pH and buffer concentration. In the past, the kinetics of these exchange reactions have been followed using isotopic labeling commonly in conjunction with such techniques as mass spectrometry, ¹⁷O NMR, and infrared spectroscopy. The mass spectroscopic method requires prior sample isolation and purification and thus lacks speed and convenience, while ¹⁷ NMR suffers from poor accuracy because of low sensitivity. The infrared method, which is based on the occurrence of well resolved bands due to carbonyl stretching of the ¹⁶O-and¹⁸O-containing species, can be hampered by solvent interference and slowness of scan of conventional dispersion spectrometers.
