摘要：

Constituting a novel synthetic route to model compounds for titanium catalysts immobilized on silica, the disilylated silsesquioxane derivative Cy7Si7O9(OH)(OSiMe3)(2) 2a, has been reacted with the 'tucked-in' fulvene complex Cp*Ti(C5Me4CH2) to give the titanium(III) silsesquioxane Cp*Ti-2[Cy7Si7O10(OSiMe3)(2)] 3, while treatment of Cp*Ti(C5Me4CH2) with Cy7Si7O9(OH)(2)(OSiMe3) 2b affords the mono(pentamethylcyclopentadienyl) complex Cp*Ti[Cy-7-Si7O11(OSiMe3)][Cy7Si7O10(OH)(OSiMe3)] 4 which is an advanced model compound for a catalytically active titanium center on a silica surface.
