Procedure
A solution of trimethylolpropane tris(mercaptopropionate) (4.0 grams, 0.010 mol.) in carbon tetrachloride (10 milliliters) was added dropwise to a slurry of N-chlorosuccinimide (4.15 grams, 0.031 mol.) and carbon tetrachloride (30 milliliters) in a 3-neck round bottom flask equipped with a magnetic stir-bar, nitrogen inlet, pressure-equalizing dropping funnel and a thermocouple. The exothermic reaction was controlled to less than 27° C. using an ice-bath. The mixture was allowed to stir at ambient temperature for an additional 5 hours. The reaction mixture was filtered to remove succinimide by-product to give a yellow solution of trimethylolpropane tris(3-sulfenylchloropropionate). 1H NMR (CDCl3) δ: 4.09 (s, 6H), 3.37 (m, 6H), 2.89 (t, J=6.5 Hz, 6H); 1.52 (q, J=6.5 Hz, 2H); 0.96 (t, J=7.4 Hz, 3H). 13C NMR (CDCl3): 170.8, 64.2, 41.4, 36.7, 33.7, 23.3, 7.8 ppm.
