sulfateester
A sulfate ester is an ester of sulfuric acid. In organic terms, it is formed when an alcohol is esterified with sulfuric acid, producing monoesters such as alkyl hydrogen sulfates (R-O-SO3H) and diesters such as dialkyl sulfates (R-O-S(=O)2-O-R'). The characteristic functional group is the OSO3 moiety, with sulfur in the +6 oxidation state. Representations commonly take the form R-O-S(=O)2-O-R' for diesters, and R-O-SO3H for monoesters.
Common examples include ethyl sulfate (ethyl hydrogen sulfate), phenyl sulfate, and the industrially important dialkyl sulfates
Preparation and interconversion: sulfate esters are typically prepared by reacting alcohols with sulfuric acid or with
Reactivity and applications: sulfate esters act as leaving groups in various substitution reactions and are important
