Alkyne metathesis catalysts composed of molybdenum(VI) propylidyne and multidentate tris(2‐hydroxylbenzyl)methane ligands have been developed, which exhibit excellent stability (remains active in solution for months at room temperature), high activity, and broad functional‐group tolerance. The homodimerization and cyclooligomerization of monopropynyl or dipropynyl substrates, including challenging
已开发出由钼(VI)丙炔和多齿三(2-羟基苄基)甲烷配体组成的炔烃复分解催化剂,具有出色的稳定性(在室温下在溶液中可保持活性数月),高活性和宽泛的官能团耐受性。单丙炔基或二丙炔基底物(包括具有挑战性的杂环底物(例如吡啶))的均二聚和环寡聚在封闭系统中于40–55°C下有效进行。已经研究了配体的结构和催化活性的关系,这表明多齿酚配体的邻位对这种催化剂体系的稳定性和活性至关重要。
