Reaction Conditions

Reaction Steps

Dithiobenzoic acid (6.3 g) and 4-chloro-a-methylstyrene (6 g) were combined and the mixture heated at 70° C. overnight. The residue was subjected to column chromatography (Kieselgel-60, 70-230 mesh, n-hexane as eluent) which gave the title compound as a purple solid (34.2% yield) m.p. 77-78° C. 1H-nmr (CDCl3) d (ppm): 1.97 (s, 6H, 2×CH3), 7.20-7.52 (m, 7H, ArH) and 7.86 (d, 2H, ArH). 13C-nmr (CDCl3) d (ppm): 28.4, 55.7, 126.5, 128.1, 131.9, 132.4, 142.8, 146.0. The signal due to C═S (d>220.0 ppm) was beyond the frequency range of the spectrum.
