A regiodivergent Ni-catalyzed amidation of unactivated secondary alkyl bromides is described. The site-selectivity of the amidation event is dictated by subtle differences on the ligand backbone, allowing introduction of the amide function at either the original sp3 carbon-halide bond or at distal sp3 C-H sites within an alkyl side-chain via chain-walking scenarios.
XtalFluor-E, an efficient coupling reagent for amidation of carboxylic acids
Orliac, Aurélie,Gomez Pardo, Domingo,Bombrun, Agnès,Cossy, Janine
supporting information, p. 902 - 905 (2013/03/29)
Amides were produced from carboxylic acids and amines by using XtalFluor-E as an activator. Even poorly reactive carboxylic acids can be transformed to amides. In addition, optically active amines and/or carboxylic acids were not epimerized/racemized during the process.
