Reaktionsschritte
Acetophenone (30 grams; 0,25 mol), methyl p-methyltoluate (136 grams; 1.0 mol), xylene (300 ml) and sodium methoxide (17.3 grams; 0.3 mol) were placed into a four-necked round bottom one liter flask equipped as in Example 1. The mixture was heated with stirring to 135°-140° C. and maintained there for 6 hours under a blanket of nitrogen. The procedure set forth in Example 1 was used to recover the desired product, benzoyl p-methylbenzoylmethane (40 grams; 67 weight percent yield) having a purity of 66%.
