B. Solvolysis of Phosphoric Acid Derivatives.—Interest continues in neighbouring-group participation in the solvolysis of phosphate esters. As a potential model compound for investigating the mechanism of ribo-nuclease action, the phenyl hydrogen phosphate ester of c/j-3,4-tetrahydro-furandiol (24) has been the subject of a detailed study. Above (and probably also below) pH 4 hydrolysis gives solely the cyclic phosphate (25)... [Pg.100]

Just as intramolecular catalysis has been observed in the hydrolysis of carboxylate esters, a variety of neighbouring groups can participate in the hydrolysis of phosphates. The alkaline hydrolysis of dimethyl phosphoacetoin [47] has found to be ca. 2 x 106 times faster in water at 25°C than that of... [Pg.200]
