Abstract

Tantalum good, titanium bad: This appears to be the case for silica- supported catalysts for the asymmetric epoxidation of allyl alcohols. Complexes such as [SiO-Ta(OEt)4] were prepared from silica and [Ta(=CHCMe3)(CH2CMe3)3], and in the presence of a tartrate and an alkyl hydroperoxide, these surface tantalum compounds lead to efficient and convenient catalysts for the asymmetric epoxidation of 2-propen-1-ol (R = H) and trans-2-hexen-1-ol (R = nPr; see reaction).
