Mechanism of Acid-Catalyzed Proton Exchange in Amides
Perrin, Charles L.,Johnston, Eric R.
, p. 4697 - 4703 (1981)
The kinetics of acid-catalyzed proton exchange in a series of primary amides were studied by NMR.The saturation-transfer method measures independently all six rate constants for exchange among sites HE, HZ, and solvent OH (usually et

Paragraph 0517-0520, (2021/03/31)
The invention discloses an efficient nitriding reagent and application thereof, wherein the nitriding reagent comprises nitrogen oxide, an active agent, a reducing agent and an organic solvent. By applying the nitriding reagent, nitrogen-containing compounds such as amide, nitrile and the like can be produced, and the method is simple in condition, low in waste discharge amount and simple in reaction equipment.

The Schmidt reaction has been an efficient and widely used synthetic approach to amides and nitriles since its discovery in 1923. However, its application often entails the use of volatile, potentially explosive, and highly toxic azide reagents. Here, we report a sequence whereby triflic anhydride and formic and acetic acids activate the bulk chemical nitromethane to serve as a nitrogen donor in place of azides in Schmidt-like reactions. This protocol further expands the substrate scope to alkynes and simple alkyl benzenes for the preparation of amides and nitriles.
