Reactivity towards hydrolysis
WebThe basic hydrolysis of esters is known as saponification. Reaction of Amides. Amides are less reactive and do not participate in most reactions. Amides are stable towards the water. Amides can be hydrolysed to carboxylic acids in the presence of acid or base. Primary and secondary amides do not react favourably with carbon nucleophiles. WebPhosphate diesters are, in general, exceedingly unreactive compounds, but their reactivity towards hydrolysis depends strongly on the basicity of the leaving group. As a result the difference in reactivity between diester and monoester monoanions decreases rapidly as the basicity of the leaving group decreases, and with very good leaving groups ...
