Catalytic activity
First, in order to achieve the suitable reaction conditions,
the reaction parameters were optimized in the epoxidation
of cyclooctene.
Effects of oxidants on the epoxidation of cyclooctene
catalyzed by [Ru(salophen)Cl@chitosan]
Different oxygen donors such as NaIO4, H2O2, H2O2/
urea (UHP), tert-BuOOH, NaClO, and Bu4NIO4 were
used for the epoxidation of cyclooctene in the presence
of [Ru(salophen)Cl@chitosan]. The results showed that
NaIO4 is the best oxidant because of its good oxidation conversion
and inertness in the absence of catalyst (Table 1).
