The reaction of β-hydroxychalcone with lead tetraacetate gave benzil. The reaction of 4,4′-dimethoxy-β-hydroxychalcone gave 2-acetoxy-1,3-di(p-methoxyphenyl)propan-1,3-dione and 4,4′-dimethoxybenzil. The reactions of 2-acetoxy-1,3-diarylpropan-1,3-diones yielded 2,2-diacetoxy-1,3-diarylpropan-1,3-diones and benzils respectively. The formation of the benzils from β-hydroxychalcones and 2-acetoxy-1,3-diarylpropan-1
β-羟基查尔酮与四乙酸铅反应生成苄基。4,4'-二甲氧基-β-羟基查尔酮反应生成2-乙酰氧基-1,3-二(对甲氧基苯基)丙-1,3-二酮和4,4'-二甲氧基苄基。2-乙酰氧基-1,3-二芳基丙-1,3-二酮的反应分别生成2,2-二乙酰氧基-1,3-二芳基丙-1,3-二酮和苄基。通过对 14C 氧化的研究,β-羟基查尔酮和 2-乙酰氧基-1,3-二芳基丙烷-1,3-二酮形成苯偶氮分别涉及 1,2-芳基和 1,2-芳酰基迁移-标记的化合物。
