Abstract
Well-defined titanosiloxane molecules with tetrahedrally coordinated Ti centers were synthesized by using monosilanol-functionalized siloxane cages as building blocks. The Ti sites are modified with -OSi(OSi)3 units, which is analogous to Ti-containing zeolites. Such titanosiloxane molecules are important as models for Ti-containing silica-based catalysts.
