Abstract Reduction of aroyl chlorides carried out in DMF with samarium metal has been studied. Samarium metal, which requires not any intended activation or pretreatment, was found to react with aroyl chloride in a controllable manner. Correspondingly, O‐aroylbenzoins, 1,2‐diarylethanones, or (Z)‐α,α′‐stilbenediol dibenzoates were afforded as the major products under controlled conditions.
摘要 研究了在 DMF 中用金属钐还原芳酰氯。发现不需要任何预期活化或预处理的钐金属以可控方式与芳酰氯反应。相应地,在受控条件下,主要产物为 O-芳酰基安息香、1,2-二芳基乙酮或 (Z)-α,α'-二苯乙烯二苯甲酸酯。
