Description

General description

N,N-Dimethylformamide diethyl acetal undergoes Me₃SiCl-mediated three-component coupling reaction with alkyne to yield 2,3,4,5-tetrasubstituted pyridine derivatives.

N,N-Dimethylformamide diethyl acetal (DMF diethyl acetal) on reaction with butanol affords N,N-dimethylformamide dibutyl acetal. It participates in various alkylation, formylation, and aminomethylenation reactions. It has been synthesized from N,N-dialkyl(chloromethylene)ammonium chloride.

Application

N,N-Dimethylformamide diethyl acetal is a suitable reagent for the esterification of fatty acids. It is suitable reagent used in the quantification of cocaine and its primary metabolite, benzoyl ecgonine, from a urine matrix by gas chromatography.
