Metallosilicates prepared by non-hydrolytic condensation reactions
Original language description
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 polycondensation reactions led to the formation of Si-O-Ti bonds and to release of acetic acid ester and diethylacetamide as byproducts, respectively. Then the catalytic activity of xerogels in epoxidation of cyclohexene was studied. Alumosilicates were prepared by reactions between Al(NMe2)3 or Al(OiPr)3 and acetoxysilanes R4-nSi(OAc)n, n = 1-4 and R = Me, Ph, H, OtBu. In this case these non-hydrolytic condensation reactions proceeded with the formation of Si-O-Al networks and dimethylacetamide or acetic acid ester and as byproducts as well
