  Synthesis and crystal structures of two bulky bis(amido)germylenes

  摘要：

  A new bulky secondary amine, HN(Dip){C(H)Ph-2} (Dip=C6H3Pr2i-2,6), has been prepared. This and a related amine, HN(Dip)(Mes) (Mes=mesityl), have been utilized in the formation of bulky lithium amides, which when added to a source of GeCl2 have yielded two new, bulky bis(amido)germylenes, [Ge{N(Dip)(Mes)}(2)] and [Ge{N(Dip)[C(H)Ph-2]}(2)], both of which have been crystallographically characterized and shown to be two-coordinate monomers.

  partially dehydroxylated at 300 °C leads to the formation of the surface imido complex (≡SiO)2Ta(═NtBu)(CH2CMe2Ph) as a major species, which was characterized with EXAFS, 13C CP/MAS NMR, diffuse reflectance FTIR, elemental analyses, and chemical reactivity. The obtained material acts as an efficient heterogeneous catalyst for various oxo/imido heterometathesis transformations: imidation of ketones and DMF with

  The presence of redox innocent metal ions has been proposed to modulate the reactivity of metal ligand multiple bonds; however, insight from structure/function relationships is limited. Here, alkali metal reduction of the Fe(III) imido complex [Ph2B(tBuIm)2Fe═NDipp] (1) provides the series of structurally characterized Fe(II) imido complexes [Ph2B(tBuIm)2Fe═NDippLi(THF)2] (2), [Ph2B(tBuIm)2Fe═NDippNa(THF)3]

  已经提出氧化还原无害金属离子的存在来调节金属配体多键的反应性；然而，对结构/功能关系的了解是有限的。在这里，碱金属还原 Fe(III) 亚氨基配合物 [Ph 2 B( t BuIm) 2 Fe=NDipp] ( 1 ) 提供了一系列结构特征化的 Fe(II) 亚氨基配合物 [Ph 2 B( t BuIm) 2 Fe=NDippLi(THF) 2 ] ( 2 )、[Ph 2 B( t BuIm) 2 Fe=NDippNa(THF) 3 ] ( 3 )、[Ph 2 B( tBuIm) 2 Fe=NDippK] 2 ( 4 )，其中碱金属阳离子配位亚氨基配体。结构研究表明，碱金属离子适度延长了 Fe=N 键距与电荷分离络合物 [Ph 2 B( t BuIm) 2 Fe=NDipp][K(18-C-6)THF 2 ] ( 5 )，对于最小的碱金属离子观察到最长的键。与5相比， 2 – 4中的亚氨基配体可以质子化和烷基化得到
