WebThe DMF byproduct then repeats the reaction with additional thionyl chloride to prepare the Vilsmeier reagent as the source of “naked” chloride. As you can see, the quaternary ammonium chloride route is much more efficient. In the case of DMF catalysis, the carboxylic acid has a choice of two electrophilic reagents for reaction. WebThis structure undergoes an acyl substitution with the liberated chloride, forming the acid anhydride and releasing regenerated molecule of DMF. Relative to thionyl chloride, oxalyl chloride is more expensive but also a milder reagent and therefore more selective. Other laboratory methods. Acid chlorides can be used as a chloride source.
