Heterogenous Alkene Epoxidation Catalysts Derived via Immobilization of Tripodal Titanium Silsesquixane Complexes

In this proposal, we describe strategies for the design of heterogeneous catalysts incorporating tripod Ti silsesquioxane moieties, and for fully assessing the synthetic potential of the resulting catalysts in the epoxidation of demanding substrates. Moreover, we describe concepts which should allow their use in alkene epoxidation u~ing HZ0 2 and HzI02 as the oxidant. The Ultimate goal of the proposed research is the design and preparation of heterogeneous alkene ,~xidation catalysts possessing improved activity, selectivity, and durability relative to current catalyst!
