N-Tosylhydrazine-mediated deoxygenative hydrogenation of aldehydes and ketones catalyzed by Pd/C
摘要:
A mild and efficient method for the deoxygenative hydrogenation of aldehydes and ketones has been developed. The reaction is mediated by N-tosylhydrazine with H-2 (1 atm) as the reductant and 10% Pd/C as the catalyst. (C) 2013 Elsevier Ltd. All rights reserved.

A new method for the synthesis of phenanthrenes via ligand-free CuBr2-catalyzed coupling/cyclization of terminal alkynes with N-tosylhydrazones derived from o-formyl biphenyls has been developed. This new synthesis has wide range of functional group compatibility.
