Procedure

The benzil was synthesized according to the procedure of Example 41, Step 3 using the benzoin of Step 4 (1.6 g, 5 mmol) and bismuth oxide (2.9 g, 6 mmol) in acetic acid (16 ml). There was obtained 1.5 g (95%) of the desired benzil as a crystalline solid: mp 132-134° C. Anal. Calc'd. for C18H18O3S (MW 314.40): C, 68.76; H, 5.77; S, 10.20. Found: C, 68.70; H, 5.81; S, 10.25.
