  SmCp2, which is easily prepared from SmI2, has been screened as a reducing agent for organic chemistry. In particular, SmCp2 promotes the pseudo-Barbier reaction between carbonyl compounds (aldehydes and ketones) and aliphatic or allylic halides more efficiently than does SmI2.

  容易从SmI 2制备的SmCp 2已被筛选为有机化学的还原剂。特别是，SmCp 2比SmI 2更有效地促进羰基化合物（醛和酮）与脂族或烯丙基卤化物之间的拟Barbier反应。

  challenging intramolecular hydroacyloxylation reaction. Both HFIP and an internal carboxy group have been proven to be crucial for the successful implementation of this transformation; these are proposed to assist the formation and stabilization of the key cationic intermediate via hydrogen-bonding interactions with perrhenate anion (ReO4–).

  该出版物描述了 Re 2 O 7在六氟异丙醇 (HFIP) 中的应用，用于活化惰性和电子失活的烯烃，以促进具有挑战性的分子内加氢酰氧基化反应。HFIP 和内部羧基均已被证明对于成功实施这一转变至关重要；这些被提议通过与高铼酸盐阴离子 (ReO 4 – )的氢键相互作用来帮助关键阳离子中间体的形成和稳定。
