Abstract
Oxidation of sulfenyl substituted tricarbonyl(eta(6)-arene)chromium(0) complexes with Ti(OPri)(4) / diethyl tartrate / H2O / cumene hydroper oxide (2:4:2:1.3) gives sulfinyl substituted tricarbonyl(eta(6)- arene )chromium(0) complexes in 60-73% yield and 81-86% e.e. (29-60% yield a nd 90-greater than or equal to 95% e.e. after crystallisation); diethy l L-(+)-tartrate was shown to lead to complexes of R configuration.
