Leuckart wallach reaktion mechanism
The Leuckart reaction is the chemical reaction that converts aldehydes or ketones to amines by reductive amination in the presence of heat. The reaction, named after Rudolf Leuckart, uses either ammonium formate or formamide as the nitrogen donor and reducing agent. It requires high temperatures, usually See more. Wallach Reaction. A Leuckart–Wallach reaction of the 3,7-dioxo-3,5,6,7-tetrahydro-2H derivative of the 1,9a,9-benzologue of (3) furnished a 7-formylamino derivative .
Die Leuckart-Wallach-Reaktion ist eine Namensreaktion der organischen Chemie und nach den deutschen Chemikern Rudolf Leuckart und Otto Wallach benannt.

The Leuckart reaction is very important in the synthesis of ATS because it is a method that is generally applicable to the synthesis of a wide range of amphetamines from starting materials that can be readily sourced by legal or illegal means (i.e. PP and its analogues).
