Dt. On et al., EPOXIDATION OF ALKENES OVER NEW AMORPHOUS MATERIALS CONTAINING DIFFERENT ACIDIC FUNCTIONS, Chemical communications, (10), 1996, pp. 1161-1162
Titania-silica mixed oxides with different trivalent cations, such as
B3+ or Al3+, are synthesized using a simple route; these catalysts are
very active in epoxidation of alkenes and selective in alpha-diol for
mation.
