How is carboxylic acid used to make DEET?
In this experiment DEET is synthesized from m-toluic acid that has undergone a nucleophilic acyl substitution with thionyl chloride. The nucleophilic acyl substitution proceeds by having the carboxylic acid on m-toluic acid attack the thionyl chloride as a nucleophile1.
