Mechanisms of hydrolysis and

The mechanism of hydrolysis and alcoholysis has been described, and the greater reactivity of the 4-position over the 2-position is attributed to the greater stability of the transition complex (20) with respect to (21), hence its greater ease of formation. The hydrolysis... [Pg.269]

The kinetic and thermodynamic properties of Fischer-type carbene complexes have also been addressed by Bernasconi, who relates the strength of the 7r-donor substituent to the thermodynamic acidity [95-101] and the kinetics and mechanism of hydrolysis and reversible cyclization to differences in the ligand X [96,102]. [Pg.7]

Ring opening reactions are the main feature of a brief review (though with 69 references) of kinetics and mechanisms of hydrolysis and substitution reactions of platinum(II) complexes (219). [Pg.100]

A novel mechanism of hydrolysis, and one of distinct pharmacological significance, has recently been uncovered in the biotransformation of glyceryl trinitrate [27], In a series of primary alkyl nitrites at pH 7.6 and 28°, f1/2... [Pg.560]

Investigations into the mechanism of hydrolysis and alcoholysis of acyl halides have been largely concerned with acyl chlorides and in particular with benzoyl chloride and the related aromatic acid chlorides. This was a result of the relatively slow rate of hydrolysis of benzoyl chloride compared with acetyl chloride (although their alcoholysis rates are easily measurable) and it is only comparatively recently90 that stop-flow techniques have been used to measure the faster rate of hydrolysis. However, in spite of this limitation, considerable progress has been made towards elucidation of the mechanism or mechanisms of hydrolysis and alcoholysis of these halides. [Pg.226]

The rates and mechanisms of hydrolysis and transesterification of phenyl benzoate in aqueous ethanolic KOH solution were determined by non-linear least-squares regression.4 Kinetic studies of the transesterification of a series of 4-nitrophenyl 3- and 4-substituted benzoates by 4-chlorophenol in DMF in the presence of potassium carbonate at various temperatures were reported.5... [Pg.55]
