A nickel-catalyzed aryl thioether metathesis has been developed to access high-value thioethers. 1,2-Bis(dicyclohexylphosphino)ethane (dcype) is essential to promote this highly functional-group-tolerant reaction. Furthermore, synthetically challenging macrocycles could be obtained in good yield in an unusual example of ring-closing metathesis that does not involve alkene bonds. In-depth organometallic
已经开发出镍催化的芳基硫醚复分解反应来获得高价值的硫醚。1,2-双(二环己基膦基)乙烷(dcype)对于促进这种高度官能团耐受的反应至关重要。此外,在不涉及烯键的闭环易位的不寻常实例中,可以高收率获得具有合成挑战性的大环化合物。深入的有机金属研究支持产物形成的可逆Ni0 / NiII途径。总体而言,这项工作不仅为以前的基于Pd的催化体系提供了更可持续的替代方法,而且还提出了与异常单键易位反应的进一步开发和应用高度相关的新应用和机理信息。
