The invention provides a method for preparing sulfur-containing compounds, the method comprising reacting a donor compound comprising at least one sulfur having at least one lone pair of electrons, with an acceptor compound; wherein the reaction occurs in the presence of an amine, optionally an amine catalyst, capable of activating the sulfur having at least one lone pair of electrons; and wherein the reaction occurs via the formation of an transient intermediate species, optionally a transient intermediate species, between the amine, optionally the amine catalyst and the donor compound; and wherein the donor compound is selected from the group consisting of a sulfurous acid, a sulfenic acid and a sulfinic acid or a salt, ester or amide of a sulfurous acid, a sulfenic acid and a sulfinic acid. The invention also provides sulfur-containing compounds of the formula: wherein R is selected from: (a) 1 -(4-Nitro-phenyl)-3-oxo-3-phenyl-propane; (b) 2-(3-Methyl-4-nitro-isoxazol-5-yl)-1 -phenyl-ethane; (c) 1-(4-Methoxy-phenyl)-2-(3-methyl-4-nitro-isoxazol-5-yl)-ethane; (d) 2-(3-Methyl-4-nitro-isoxazol-5-yl)-1-(4-nitro-phenyl)-ethane; (e) 1-(4-Fluoro-phenyl)-2-(3-methyl-4-nitro-isoxazol-5-yl)-ethane; (f) 1 -(4-Chloro-phenyl)-2-(3-methyl-4-nitro-isoxazol-5-yl)-ethane; and (g) 3-Oxo-cyclohexane. Finally, the invention provides use of chiral sulfur-containing compounds obtainable by the above-mentioned method or chiral sulfur-containing compounds as mentioned above for the resolution of racemic mixtures of amines.

(CF6)-based chiral stationary phases (CSPs) bind barium cations. As a result, the barium-complexed CSPs exhibit enantioselectivity toward 16 chiral phosphoric and sulfonic acids in the polar organic mode (e.g., methanol or ethanol mobile phase containing a bariumsalt additive). Retention is predominantly governed by a strong ionic interaction between the analyte and the complexed barium cation as well as hydrogen
