What is the Eschweiler-Clarke reaction?

Eschweiler- Clarke reaction is a substitution organic chemistry reaction which leads to the formation of tertiary methylamines by reaction of primary amine or secondary amine in presence of formaldehyde and formic acid. The reaction was discovered by German chemist Wilhelm Eschweiler as well as British chemist Hans Thacker Clarke.

What is the difference between Eschweiler Clarke and Wallach’s procedure?

The Wallach procedure employs formic acid as the reducing agent < 49OR (5)301 >. The Eschweiler–Clarke procedure uses a mixture of formaldehyde and formic acid, thereby affording RNMe 2 and R 2 NMe from RNH 2 and R 2 NH, respectively < 71JOC829 >.

How do you convert RNH2 to NME in Eschweiler Clarke?

The Eschweiler–Clarke procedure uses a mixture of formaldehyde and formic acid, thereby affording RNMe 2 and R 2 NMe from RNH 2 and R 2 NH, respectively < 71JOC829 >. The same conversions can be accomplished by treating the amine with aqueous formaldehyde and NaBH 4 or NaBH 3 CN < 77TL3469 >.

What is the history of Eschweiler method?

It is named for the German chemist Wilhelm Eschweiler (1860–1936) and the British chemist Hans Thacher Clarke (1887-1972). The first methylation of the amine begins with imine formation with formaldehyde. The formic acid acts as a source of hydride and reduces the imine to a secondary amine.

Where did the name Eschweiler come from?
