S. Thorimbert et al., SELECTIVE HETEROGENEOUS EPOXIDATIONS WITH CP-TITANIUM CHLORIDE DERIVED MICROPOROUS SILICA GLASSES, Tetrahedron, 51(13), 1995, pp. 3787-3792
A new heterogeneous epoxidation catalyst is prepared by the copolycond
ensation of cyclopentadienyl titanium chlorides with tetraethoxysilane
by a modified sol-gel procedure. Epoxidations of non-activated olefin
s in the presence of these new heterogeneous catalysts are described.
