Hydrolytic reactions of inorganic esters

From the aspects of widespread occurrence, phosphate and sulphur esters are of the greatest importance. The study of hydrolysis of monophosphate esters shows that alcohol or phenolic forms split more readily 

Cyclic phosphenium salts also undergo the alkaline hydrolysis 

Hydrolytic reactions of inorganic esters of sulphur can be illustrated by several typical examples. Monoesters react as follows  

In this way chemical degradation of, for example, tensides, can take place. A similar reaction is that of thioesters  

CH30-C6H4-S=0 + CH3O-C6H4-SO2H — solvolysis products.
