Title: Synthesis and development of Chitosan anchored copper(II) Schiff base complexes as heterogeneous catalysts for N-arylation of amines.
Authors: Anuradha, null1, Kumari, Shweta1, Pathak, Devendra D.1 ddpathak@yahoo.com
Source: Tetrahedron Letters: International Organ for the Rapid Publication of Preliminary Communications in Organic Chemistry. Jul2015, Vol. 56 Issue 27, p4135-4142. 8p.
Subjects: Chitosan, Copper compounds, Schiff bases, Metal complexes, Heterogeneous catalysts, Arylation, Amines, Inorganic synthesis
Abstract: The Chitosan anchored Cu(II) Schiff base complexes (C 1 –C 3 ) have been synthesized and characterized by FTIR, UV, FE-SEM, EDAX, TGA, AAS and elemental analysis. These complexes have been found to be efficient and recyclable heterogeneous catalysts for the Chan–Lam C–N coupling reaction of various aromatic/aliphatic amines with arylboronic acid under mild reaction conditions. These complexes can be easily filtered out from the reaction medium and reused up to five times without significant loss of catalytic activity. [ABSTRACT FROM AUTHOR]
