Angew.Chem.Int.Ed.2013,52,10845~10849官能团化氮杂环卡宾在金属有机化学和均相催化研究中得到了广泛应用.结合氮杂环卡宾配体和硅基配体强给电子性质的硅基官能化的氮杂环卡宾配体是一类理想的具有更强给电子能力的配体.然而由于亲核性氮杂环卡宾与路易斯酸性硅烷容易发生多种反应,如生成酸碱加合物,发生硅氢键插入反应,扩环反应等,硅基官能化的氮杂环
Angew.Chem.Int.Ed.2013,52,10845 ~ 10849 The functionalized azacyclic carbenes have been widely used in metalorganic chemistry and homogeneous catalysis. Combining the nitrogen-heterocyclic carbene ligand and silicon-based ligand Electronically functionalized silicon-based azacyclic carbene ligands are an ideal class of ligands with stronger electron donating ability, however, due to the variety of reactions between nucleophilic azacyclic carbenes and Lewis acid silanes, Acid-base adducts, silicon-hydrogen bond insertion reactions, ring expansion reactions, silicon-functionalized nitrogen heterocycles
