Dioxomolybdenum(VI) epoxidation catalyst supported on mesoporous silica containing phosphane oxide groups

A new mesoporous hybrid material (denoted LP-TEPPPOMo) has been prepared by tethering [MoO2Cl2] onto mesoporous silica previously functionalised with phosphane oxide spacer ligands. The LP-TEPPPO-Mo material was tested in the liquid-phase epoxidation of olefins [cis-cyclooctene, (R)(+)-limonene, trans-2-octene and 1-octene] with tBuOOH, at 55 °C, and without a co-solvent, giving at least 90 % selectivity to the corresponding epoxide at 36-77% conversion: in the case of limonene, regioselectivity favours the epoxidation of the endocyclic double bond, giving mainly 1, 2-epoxy-p-menth-8-ene. The catalytic system based on a liquid-liquid biphasic system containing the homogeneous complex [MoCl2(O) 2(OP(CH2CH3)(Ph)2J2] dissolved in the ionic liquid 1butyl-4-methylpyridinium tetrafluoroborate leads to lower epoxide selectivity (91 % at 64 % conversion) in the reaction of cyclooctene in comparison to that observed for LPTEPPPO-Mo (100% at 87% conversion). The reused solidliquid and liquid-liquid biphasic catalytic systems show partial loss of catalytic activity.
