Tetranuclear Zn complex covalently immobilized on sulfopropylsilylated mesoporous silica: An efficient catalyst for ring opening reaction of epoxide with amine
Abstract Tetranuclear Zn complex,[Zn 4 (L) 2 (LH) 2 ((CH 3) 2 SO) 2]· 2CH 3 OH·(CH 3) 2
SO· H 2 O (1)[where LH 3= 3-(E)-(2-hydroxyphenylimino) methyl-4-hydroxy-5-
hydroxymethylphenyl (LH 3)] was prepared and characterized by single-crystal X-ray
analysis. Then, it was incorporated to the sulfopropylsilylated MCM-48, MCM-41 and SBA-
15 mesoporous silica materials. The prepared materials were thoroughly characterized by
XRD, FT-IR, N 2 adsorption/desorption analysis, NH 3-TPD, TGA, SEM-EDX and ICP-OES …
