摘要
Catalytic hydrogenation of (2-nitrophenyl)acetonitriles bearing an electron-withdrawing substituent alpha to the nitrile, using Pd/C and (Ph3P)(4)Pd, affords N-hydroxy-2-aminoindoles in good to excellent yields. (Ph3P)4Pd decreases the reduction rate of the intermediate hydroxylamine and acts as a catalyst during the cyclization onto the nitrile. (c) 2005 Elsevier Ltd. All rights reserved.
