Tuning of reactivity in epoxidation of alkenes by iron and ruthenium complexes associated to non-porphyrinic ligands
Abstract
RuCl3·n(H2O) or FeSO4 associated with bipyridyl or substituted phenanthrolines, catalyse the expoxidation of stilbenes by IO4– or ClO–; using phenanthrolines bearing electron donating or withdrawing groups, it is possible to modulate the reactivity of these systems.
