Loudon, J. D. published the artcileElimination of sulfinate from sulfonic esters, HPLC of Formula: 13312-84-0, the publication is Journal of the Chemical Society (1959), 1780-2, database is CAplus.
In a typical experiment, 1.4 g. 2-ClC6H4CHO, 1.9 g. 4-MeC6H4SO2Cl, 2 cc. dioxane, and 4 cc. H2O, at 5° treated with 0.66 g. KCN, the mixture stirred 1 h., the solid filtered off, dissolved in 5 cc. 2:2:1 Me2CO-EtOH-H2O, filtered, and the filtrate treated with 3 g. ice gave 78% 2-ClC6H4CH(CN)OSO2C6H4Me-4 (I), m. 86° (EtOH). In similar fashion were prepared the following RCH(CN)OSO2C6H4Me-4 derivatives (R, % yield, and m.p. given): Ph(Ia), 72, 60°; 2-BrC6H4, 75, 104°; 3-MeOC6H4, 55, 52°: 2-O2NC6H4(II), 72, 111°; 2,4-Cl2C6H3, 72, 78°; 2,5-Cl(O2N)C6H3, 70, 118°. PhCH(CN)OSO2C6H3Cl2-2,5, -, 102°, and 4-ClC6H4CH(CN)OSO2C6H3Cl2 -2,5, -, 86°, were also prepared II (1.66 g.) in 10 cc. EtOH kept 0.25 h. with 0.12 g. Na in 2 cc. EtOH, concentrated in vacuo, and the residual material extracted with C6H6 left 0.77 g. 4-MeC6H4SO2Na(III) and the C6H6 solution chromatographed on alumina gave 0.68 g. O2NC6H4CO2Et (IV), m. 30°. All the above compounds gave good yields of the corresponding Na sulfinate. When the NaOEt in the experiment with I was replaced by NaCH(CO2Et)2, the products were III, IV, and 2-O2NC6H4CH(CN)SO2C6H4Me-4(V), m. 167°. I (1.5 g.) and 5 cc. Et3N 0.5 h. at 100° gave 2-ClC6H4CH(CN)SO2C6H4Me-4(VI), m. 112°, and 2-ClC6H4CO2Et. PhSO2NPh(CH2Bz) (0.73 g.) in 10 cc. EtOH and 0.046 g. Na in 3 cc. EtOH as above gave III and BzCO2Et (identified by reaction with ο-C6H4(NH2)2 as 2-phenylquinoxaline). Ia (2.87 g.), 20 cc. MeOH, and 1.53 g. NaBr refluxed 1 h. and concentrated gave 70% PhCH(CN)Br, b15 137-9°, m. 29°. I (0.32 g.), 0.13 g. 4-MeC6H4SH, and 0.04 g. NaOH in 8 cc. 4:1 EtOH-H2O refluxed 0.5 h. gave 85% 2-ClC6H4CH(CN)SC6H4Me-4. I (0.32 g.) and 0.27 g. III in 5 cc. EtOH refluxed 48 h. gave VI. I (1.6 g.) and 2 cc. anhydrous C5H5N at 0° gave the pyridinium derivative (VII), m. 101° (C6H6-petr. ether); VII and 5N NaOH gave the betaine, dark red crystals, m. 138° (EtOH). I (0.32 g.) 3 cc. AcOH, 0.05 cc. concentrated H2SO4, and 0.15 g. 10% Pd on C absorbed 3 mol equivalents H in 3 h. to give 60% 2-ClC6-H4CH2CH2NH2; picrate m. 186° (C6H6). CH2N2 (approx. 10 g.) in 50 mL. Et2O and 15.5 g. PhCH2COCl in 50 cc. Et2O kept several hrs. and 17 g. powd. 4-MeC6H4SO3H added gave after 12 h. at 20° PhCH2COCH2OSO2C6H4Me-4, m. 63° (EtOH).
