TLDR
In this article, the preparation of the eight-membered ring compounds (R 1 XTiOSiR 2 2 O) 2 was reported, and the results of different methods of the preparation were compared.
Abstract: 
The preparation by different methods of the eight-membered ring compounds (R 1 XTiOSiR 2 2 O) 2 is reported: (2: R 1 =C 5 H 5 , X=Cl, R 2 =tBu; 3: R 1 =N(SiMe 3 ) 2 , X=Cl, R 2 =tBu; 4: R 1 =C 5 Me 5 , X=Cl, R 2 =Ph; 6: R 1 =X=NEt 2 , R 2 =tBu). The six-membered ring Ph 2 SiO[OTiC 5 Me 5 (Cl)] 2 5 is formed together with 4 by the reaction of C 5 Me 5 TiCl 3 and Ph 2 Si(OLi) 2 . Compounds 2 and 4 have been characterized by X-ray structural analysis.

TL;DR: The titanosilicate materials produced at temperatures below 800 degrees C with a large number of Ti-O-Si linkages were found to be more active catalysts compared to the materials produced above 900 degrees C, and the selectivity of the epoxide formation over the other possible oxidized products was found to been very good.
