実験手順
Phenylglyoxal monohydrate (304 mg, 2 mM) and 1,2,3,4-tetramethylbenzene (0.60 ml, 4 mM were dissolved in dichloroethane (5 ml), titanium tetrachloride (0.33 ml, 3 mM) was added, and reacted at room temperature for 10 minutes. Using the same procedure as in Example 1, 2',3',4',5'-tetramethylbenzoin was obtained (378.2 mg, 70.7% yield).
