We develop herein an efficient rhodium-catalyzed remote isomerization of aromatic and aliphatic alkenyl alcohols into ketones. This catalytic process, with a commercially available catalyst and ligand ([RhCl(cod)]2 and Xantphos), features high efficiency, low catalyst loading, good functional group tolerance, a broad substrate scope, and no (sub)stoichiometric additive. Preliminary mechanistic studies
我们在本文中开发了一种有效的铑催化的芳族和脂族烯基醇远程异构化成酮的方法。该催化过程使用市售的催化剂和配体([RhCl(cod)] 2和Xantphos),具有效率高,催化剂用量低,官能团耐受性好,底物范围宽和无(亚)化学计量添加剂的特点。初步的机理研究表明,这种转变涉及迭代解离的β-氢化物消除-迁移插入过程。
