Abstract

Silica-supported chiral tantalum alkoxides are active catalysts for the asymmetric epoxidation of propenol and trans hex-2-en-1ol. The influence of different parameters on their catalytic performance was followed: the impregnation duration by a tartrate (step in their preparation); the nature of the solvent (CH2Cl2, pentane, toluene) and of the oxidant (TBHP, CHP, H2O2); poisoning effects by water or t-butanol; the reaction temperature and the substrate concentration.
