Participation of neighbouring groups in the hydrolysis of 3-hydroxy-2-pyridylmethyl phosphate
Abstract
The reactive species in the hydrolysis of 3-hydroxy-2-pyridylmethyl phosphate are the neutral zwitterion, the monoanion, and the dianion, of which the last speices is the most labile; the intramolecular catalytic effect of the hydroxy-group is much greater than that of the pyridinium group, and causes a unique rate enhancement.
