✦ Synopsis
Oxidation of sulfenyl substituted tricarbonyl(ll6-arene)chrom(o) complexes with Ti(OP& I diethyl lartraw I H20 I cumene hydroperoxide (2:4:2:1.3) gives sulfinyl suhstitured tricarbonyl(q6arcne)chromium(O) complexes in 60.73% yield and 111.86% e.e. (29.60% yield and 90.t95t c e. after cryslallisation); dietbyl L-(+)-tartrate was shown 10 lead 10 complexes of R contiguration.
