Hydrogen bonding and structure of 2-hydroxy-N-acylanilines in the solid state and in solution
Hibbert, Frank,Mills, Judith F.,Nyburg, Stanley C.,Parkins, Adrian W.
, p. 629 - 634 (1998)
In crystals of 2-hydroxy-N-benzoylaniline and 2-hydroxy-N-trifluoroacetylaniline, ribbons of molecules are held by intermolecular hydrogen bonds between the hydrpxy and carbonyl groups of adjacent molecules. The O ... H ... O bond lengths are 2.65 and 2.7

A new approach for amide bond formation via a mild and efficient Iron-catalyzed cross-coupling reaction of acylhydrazines and amines using TBHP as oxidant is described. This protocol is compatible with a wide range of amines and acylhydrazines. In addition, the synthetic application of the reaction is presented.

Herein, we report an operationally simple, cheap, and catalyst-free method for the transamidation of a diverse range of unactivated amides furnishing the desired products in excellent yields. This protocol is environmentally friendly and operates under extremely mild conditions without using any promoter or additives. Significantly, this strategy has been implied in the chemoselective synthesis of a pharmaceutical molecule, paracetamol, on a gram-scale with excellent yield. We anticipate that this universally applicable strategy will be of great interest in drug discovery, biochemistry, and organic synthesis.
