Abstract
Large differences in the ratio of sulfide versus sulfoxide oxidation of thi
anthrene 5-oxide (SSO) have been observed for heterogeneous versus homogene
ous Ti-IV catalysts; whereas the Ti-doped zeolites (heterogeneous) oxidise
by means of an electrophilic species, sulfoxide coordination (template effe
ct) fos Ti(OiPr)(4) (homogeneous) masks the true electrophilic character of
the metal oxidant. (C) 2000 Elsevier Science B.V. All rights reserved.
