Abstract: Rates of hydrolysis of the vinyl ether functional groups of 5-enolpyruvylshikimate 3- phosphate (EPSP), a-methoxyacrylic acid, and methyl a-methoxyacrylate were measured in concentrated and dilute mineral acid solutions and carboxylic acid buffers, and rate profiles were constructed from the data so obtained. The results for methyl a-methoxyacrylate show a monotonic decrease in reaction rate with decreasing solvent acidity, culminating in a first ...
