First Ln(ii) ring-expanded NHC complexes (er-NHC)Ln[N(SiMe3)2]2 (Ln = Sm, Yb) are synthesized and proved to be highly efficient pre-catalysts for the intermolecular hydrophosphination of such indolent substrates as 1-alkenes, cyclohexene and norbornene.
首次合成了环状扩环的二价镧系元素氮杂环卡宾配合物（er-NHC）Ln[N(SiMe3)2]2（Ln = Sm，Yb），并证明它们是用于1-烯烃、环己烯和降冰片烯等惰性底物分子间氢膦化反应的高效预催化剂。
