Here, we report highly active titanosilicate catalysts featuring an isolated titanium species with a uniform tetrahedral coordination state, unusually high surface density, and high accessibility of the Ti active sites. The layered titanosilicate prepared by grafting of TiIVacetylacetonate onto the surfaces of the crystalline layered silicate, HUS-7, showed excellent catalytic performance in the epoxidation of cyclohexene with tert-butyl hydroperoxide as an oxidant (turnover frequency of 230h-1and reaction rate of 314mmolg-1h-1).
