Abstract
(Chemical Equation Presented) Salen's lot: Meerwein-Ponndorf-Verley reduction of [Ti(salen) (OiPr)2] (salen = bis(salicylidene) ethylenediaminato) complexes followed by treatment with water leads to the synthesis of pseudo-heterochiral and homochiral di-μ-oxotitanium dimers. These dimers, in particular (aR,S,Δ,aR,S,Δ)-dimer 1, efficiently catalyze the epoxidation of simple olefins using aqueous hydrogen peroxide (see scheme) with ee values up to 99% and turnover numbers up to 4600.
