Go organic! N-Heterocyclic carbene (NHC) 1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene (IiPr) has been found to be an efficient and selective catalyst for the dehydrogenative coupling of a wide range of silanes and hydroxyl groups to form SiO bonds under mild and solvent-free conditions. Mechanistic studies indicated that the activation of hydroxyl groups by the NHC is the most plausible initial step for the process.
选择有机!N-杂环卡宾(NHC)1,3-二异丙基-4,5-二甲基咪唑-2-亚基(IiPr)已被发现是一种高效和选择性的催化剂,可在温和无溶剂条件下将各种硅烷和羟基脱氢偶联形成 SiO 键。机理研究表明,NHC 对羟基的活化是该过程最合理的初始步骤。
