A new heterogeneous catalytic system, phase-boundary catalysis, for epoxidation of alkene with aqueous H2O2 is proposed. Amphiphilic titanium-loaded zeolite particles, a part of the external surface of which was covered with hydrophobic alkyl groups and the rest being left hydrophilic, were prepared by deposition of titanium species from titanium(IV) tetra-2-propoxide and attachment of octadecy...
Titanocene(III)-mediated radical processes are important tools for the formation of C C bonds under mild conditions, and are compatible with many functional groups. Moreover, titanium(III) complexes can be used substoichiometrically, which has allowed the development of enantioselective versions of these reactions. A serious limitation of these radical processes, however, derives from the fact ...
