Rd. Oldroyd et al., ENGINEERING AN ATOMICALLY WELL-DEFINED ACTIVE-SITE FOR THE CATALYTIC EPOXIDATION OF ALKENES, Chemical communications, (21), 1997, pp. 2025-2026
The improvement effected by replacing one of the three O-S drop groups
to which a Ti-IV ion is anchored (to a mesoporous silica support) by
a O-G drop group is described, as is the detailed structure retrieved
by in situ X-ray absorption spectroscopy of the created active site.
