Reactions of [(MeSi)N]RE(μ-Cl)Li(THF) with aminomethylene-substituted pyridine 2-[O(CHCH)NCHCHNCH]CHN () gave the dianionic α-iminopyridine rare-earth metal amido complexes {μ-η:σ:κ:κ-2-[O(CHCH)NCHCHNCH]CHN}RE[N(SiMe)] (RE = Y(), La(), Pr(), Nd(), Sm(), Dy(), Er(), and Lu ()). However, reaction of [(MeSi)N]Y(μ-Cl)Li(THF) with pyridin-2-ylmethyl-substituted amines such as 2-(RNHCH)CHN (R = Bu () and 2,6-PrPh ()) or benzyl-substituted amine O(CHCH)NCHCHNHCHCH () afforded the corresponding yttrium complexes containing monoanionic ligands [2-(RNCH)CHN]YN(SiMe) (R = Bu () and 2,6-PrPh ()) or [O(CHCH)NCHCHNCHCH][(MeSi)N)]Y(μ-Cl)(μ-η-O(CHCH)NCHCHNCHCH)Li(THF) (). Dianionic α-iminopyridine rare-earth metal amido complexes showed high catalytic activities for the dehydrogenation coupling reaction of hydrosilanes and amines providing a variety of silylamines in high yields.
[(MeSi)N]RE(μ-Cl)Li(THF)与氨基亚甲基取代的吡啶2-[O(CHCH)NCHCHNCH]CHN（）反应，生成双阴离子α-亚氨基吡啶稀土金属酰胺配合物{μ-η:σ:κ:κ-2-[O(CHCH)NCHCHNCH]CHN}RE[N(SiMe)]（RE = Y（）、La（）、Pr（）、Nd（）、Sm（）、Dy（）、Er（）和Lu（））。然而，[(MeSi)N]Y(μ-Cl)Li(THF)与吡啶-2-基甲基取代的胺，如2-(RNHCH)CHN（R = Bu（）和2,6-PrPh（））或苄基取代的胺O(CHCH)NCHCHNHCHCH（）反应，得到了相应的含有单阴离子配体的钇配合物[2-(RNCH)CHN]YN(SiMe)（R = Bu（）和2,6-PrPh（））或[O(CHCH)NCHCHNCHCH][(MeSi)N)]Y(μ-Cl)(μ-η-O(CHCH)NCHCHNCHCH)Li(THF)（）。双阴离子α-亚氨基吡啶稀土金属酰胺配合物对硅烷和胺的脱氢偶联反应表现出高催化活性，能高产率地提供各种甲硅烷基胺。
