  Synthesis and Reactivity of Homoleptic α-Metalated N,N-Dimethylbenzylamine Rare-Earth-Metal Complexes

  摘要：

  A series of new homoleptic rare-earth-metal complexes as synthesized using salt metathesis reactions between LnCl(3) and alpha-K(DMBA) (Ln = La (1), Ce (2), Pr (3), Nd (4), Sm (5), Gd (6), Y (7); DMBA = N,N-dimethylbenzylamine). All seven complexes were found to be free of coordinating solvent, and no formation of any "-ate" species was observed. The ligands in complexes 1-7 displayed eta(4) coordination to the metal center. Subsequently, the reactivity of 1 and 7 was investigated via various protonolysis reactions using silylamines, anilines, and phenols to generate a diverse array of other homoleptic lanthanide complexes.

  α-金属化的N，N-二甲基苄基胺稀有金属配合物对异枯烯的插入反应和催化加氢磷酸化

  摘要：

  通过一系列化学计量插入和催化加氢磷酸化反应，探查了均相的α-金属化的二甲基苄基胺镧系元素络合物（α - Ln（DMBA）3； Ln = La，Y; DMBA =α-去质子化的二甲基苄胺）的反应性。两种稀土金属物种都插入了3个当量的各种碳二亚胺，以形成相应的均化eptic胺盐。α - La（DMBA）3还发现其以适中至优异的分离产率，对于杂枯烯的室温氢磷酸化以形成磷胍，磷酰脲和硫代硫脲是有用的预催化剂。此外，通过一系列逐步的化学计量质子化和插入反应，研究了氢磷化催化的合理机理。

Both rare-earth-metal species inserted 3 equiv of various carbodiimides to form the corresponding homoleptic amidinates. α-La(DMBA)3 was also found to be a useful precatalyst for the room-temperature hydrophosphination of heterocumulenes to form phosphaguanidines, phosphaureas, and phosphathioureas
