Synthesis and Catalytic Performance of Organic-Inorganic Hybrid Mesoporous Material Having Basic Nanospace.

Basic nanospace was synthesized by the homogeneous modification of FSM-16 with 3-(triethoxysilyl)pyridine, which is a rigid substrate without an alkyl chain as linker. Aldol condensation of butanal gave the corresponding dimer in high yields over 3-(triethoxysilyl)pyridine-modified FSM-16. A copper-pyridine complex was immobilized within the interior of FSM-16 using the modified pyridyl group as a ligand and the oxidative coupling polymerization of 2,5-dimethylphenol proceeded with high regio-selectivity. Graphical Abstract: Basic nanospace was synthesized by the homogeneous modification of FSM-16 with 3-(triethoxysilyl)pyridine, which is a rigid substrate without an alkyl chain as linker. Aldol condensation of n-butyraldehyde gave the corresponding dimer in high yields over 3-(triethoxysilyl)pyridine-modified FSM-16. A copper-pyridine complex was immobilized within the interior of FSM-16 using a modified pyridyl group as the ligand and the oxidative polymerization of 2,5-dimethylphenol proceeded with high regio-selectivity.[Figure not available: see fulltext.] [ABSTRACT FROM AUTHOR]
