Description

General description

Triethylamine is a tertiary amine. It has been reported as a promising precipitating reagent for phosphomolybdic acid. Et₃N/formic acid system has been used for the asymmetric transfer hydrogenation (ATH) of methoxy-substituted derivatives.

Triethylamine is a strong base and precipitating agent widely used in Heck reaction and to prepare esters and amides from acyl chlorides.

Application

Triethylamine may be used in the following studies:

• As a base for the Heck reactions.
• Synthesis of spirocycles via Heck cyclization.
• Preparation of triethylammonium picrate and 0.1M triethylamine hydrochloride.
