Synthesis of N-alkyl-N′-aryl-piperazines via copper-catalyzed C–N bond formation
摘要:
An efficient copper-catalyzed tandem synthesis of N-alkyl-N'-aryl-piperazines from 1,4-diazabicyclo[2.2.2]octane, alkyl halides, and aryl halides in the presence of copper(I) iodide and potassium tert-butoxide in DMSO is described. (C) 2014 Published by Elsevier Ltd.
