A TWO COMPONENT RECYCLABLE HETEROGENEOUS CATALYST, PROCESS FOR PREPARATION THEREOF AND ITS USE FOR PREPARATION OF AMINES

摘要

The invention describes the development of highly efficient, recyclable two component system, CuAl-hydrotalcite/rac 1,1'-Binaphthalene-2,2'-diol catalytic system for the N-alkylation of electron deficient aryl chlorides in presence of potassium carbonate as a base at room temperature in 3-6 h, wherein the process is provided for the preparation of various secondary amines via C-N coupling reaction of aliphatic amines(aliphatic open chain, acyclic, benzyl amines and heterocyclic amines) with various aryl chlorides.
