Soluble Molecular Titanosilicates

Abstract

Titanosilicates with structural characteristics similar to those of many Ti-containing zeolites were synthesized from the reactions of (arylamino)silanetriol [RSi(OH)3] with organometallic titanium precursors [Cp*TiCl3], TiCl4·2THF, and [Cp*TiMe(μ-O)]3. The product of the reaction with [Cp*TiCl3], 1, is a soluble molecular silicate in which formal TiO2 fragments are trapped inside. Cp* = C5Me5; R = (2,6-iPr2C6H3)NSiMe3.
