and scalable one-pot, three-step, pinacol-coupling–rearrangement–reduction cascade reaction useful for the formation of 2,2-diphenylethanol derivatives. The reaction is carried out in water in the presence of a commercially available and regenerable supported acid under moderate pressure. A dozen of aromatic aldehydes have been successfully submitted to the standard protocol giving the target 2,2-diarylethanol
我们在此报告了一种绿色且可扩展的一锅,三步,频哪醇偶联-重排-还原级联反应,可用于形成2,2-二苯乙醇衍生物。该反应在中等压力下在市售可再生的负载酸存在下在水中进行。十二种芳香醛已成功提交标准方案,以高收率(70-85%)得到目标2,2-二芳基乙醇衍生物。
