Abstract
In the original language
Non-hydrolytic sol-gel reactions are efficient alternatives to classical aqueous techniques for synthesis of multimetallic oxides and inorganic-organic hybrid materials. We developed non-hydrolytic sol-gel routes to several groups of metallosilicate hybrid inorganic-organic materials based on polycondensation reactions. Titanosilicate xerogels were prepared by reactions between Ti(NEt2)4 or Ti(OR)4 , R = OiPr,OtBu and Si(OAc)4. These non-hydrolytic condensation reactions lead to form Si–O–Ti bonds and to release acetic acid ester and diethylacetamide as byproducts, respectively. Then the catalytic activity for epoxidation of cyclohexene was studied.
