摘要:
A useful and convenient methodology has been developed for synthesis of mono N-arylated aliphatic 1,2- and 1,3-diamines and amino alcohols. A highly efficient and renewable heterogeneous chitosan supported copper(II) catalyst has been employed for the C-N cross coupling between aryl halides and aliphatic diamines/amino alcohols. The main advantages of this reaction are the high yields of the products, reduced reaction time, convenient work up procedure, renewability of the catalyst, and less metal contamination of the products. All these factors make the present C-N cross coupling reaction economical, green, and sustainable. (C) 2014 Elsevier Ltd. All rights reserved.
