摘要

Epoxidation is of great importance in organic synthesis due to the usefulness of oxiranes as intermediates. Substantial effort has been expended to substitute stochiometric or homogeneous transition-metal catalysed epoxidations by solid catalysed processes.1 The first really efficient heterogeneous catalyst TiOz-on-Si02, utilised for industrial propene oxide production,2 was prepared by anchoring a titanium compound onto the surface of silica support. A titanium- ...
