The synthesis of (SRSS)-[(phenylsulfinyl)benzene] chromiumtricarbonyl 5 and (SRSS)-[(p-tolylsulfinyl)benzene] chromiumtricarbonyl6 is achieved via a nucleophilic displacement reaction between the anion derived from (benzene) chromiumtricarbonyl 9 and a suitable sulfinate ester. Replacing the sulfinate ester with a chiral sulfinyl-transfer reagent allows the isolation of the non-racemic sulfinyl-substituted
