Reaction Conditions

Reaction Steps

Methyl magnesium chloride (10 mL, 3M solution in THF) was diluted with THF (10 mL) and the resulting solution warmed to 40° C. Carbon disulfide (2.28 g, 0.03 mol) was added over 10 minutes while maintaining the reaction temperature at 40° C. The reaction was cooled to room temperature before adding benzyl bromide (5.1 g, 0.03 mol) over 15 minutes. The reaction temperature was increased to 50° C. and maintained for a further 45 minutes. Water (100 mL) was added and the organic products extracted with n-hexane (3×60 mL). The combined organic extracts were washed with water, brine and dried over anhydrous magnesium sulfate. After removal of solvent and column chromatography (Kieselgel-60, 70-230 mesh, 5% diethyl ether in n-hexane eluent), pure benzyl dithioacetate was obtained as a golden oil (3 g, 55% yield). 1H-nmr (CDCl3) d (ppm): 2.90 (s, 3H); 4.46 (s, 2H) and 7.31 (m, 5H).
