실험 절차

A mixture of dithiobenzoic acid (10.59 g), a-methylstyrene (10 g) and carbon tetrachloride (40 mL) was heated at 70° C. for 4 hours. The resultant mixture was reduced to a crude oil which was purified by column chromatography (aluminium oxide (activity III), n-hexane eluent) to give 2-phenylprop-2-yl dithiobenzoate (5) (6.1 g, 32.6% yield) as a dark purple oil. 1H-nmr (CDCl3) d(ppm): 2.03 (s, 6H); 7.20-7.60 (m, 8H) and 7.86 (m, 2H).
