Abstract
CuO/aluminosilicate has been found to be an efficient catalyst for the aqueous Heck coupling of styrene with aryl halides under ligand free conditions. The catalyst (CuO/aluminosilicate) was prepared from CuCl<sub>2</sub>·6H<sub>2</sub>O, aluminium nitrate and tetraethyl orthosilicate (TEOS) and characterized by XRD, HR-TEM, SEM-EDX and XPS. The reaction conditions were optimized with different solvents, bases, catalyst amounts and temperatures using sytrene and 4-chlorobenzonitrile as a model system. The scope of the reaction was subsequently extended to include various substituted aryl halides. Regioselectivity, heterogeneity and reusability were performed.
