development of an iron(III)-catalyzed coupling of thioesters with aliphatic organomanganese reagents. The good functional group tolerance resulted in successful transformation of a range of thioesters, including biologically relevant compounds. The presence of accessible β-hydrogen atom in the organomanganese reagent seems crucial for an effective catalyst activation. The liberated thiolate stabilizes the
Remarkably simple IrIII catalysts enable the isomerization of primary and sec‐allylicalcohols under very mild reaction conditions. X‐ray absorption spectroscopy (XAS) and mass spectrometry (MS) studies indicate that the catalysts, with the general formula [Cp*IrIII], require a halide ligand for catalytic activity, but no additives or additional ligands are needed.
非常简单的Ir III催化剂可在非常温和的反应条件下实现伯醇和仲烯丙基醇的异构化。X射线吸收光谱(XAS)和质谱(MS)研究表明,通式为[Cp * Ir III ]的催化剂需要卤化物配体才能发挥催化活性,但不需要添加剂或其他配体。
