Page/Page column 6-7, (2012/01/13)
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.

(Chemical Equation Presented) Employing CuI nanoparticles as an efficient catalyst for the cross-coupling reactions of various N/O nucleophilic reagents with aryl chlorides could be successfully carried out under mild conditions in the absence of both the ligands and strong bases. A variety of products including N-arylimidazoles and aryl ethers were synthesized in good to excellent yields. 2009 American Chemical Society.

We have developed an efficient and readily available catalyst system CuBr/racemic BINOL ( 1,1′-binaphthyl-2,2′-diol) that catalyzes N-arylation of aliphatic amines at room temperature, and this inexpensive catalyst system is of high selectivity and tolerance toward various functional groups in the substrates.
