Strikingly, the analogous reaction of 1 with the lighter element analogue Cp3Ce affords the acyclic product [Cp3CeSi(SiMe3)2SiMe2SiMe2Si(SiMe3)2-Cp3Ce]2–2[K(18-cr-6)]+ (3) as the first example of a complex featuring a Ce–Si bond.

  The synthetic chemistry leading to tris(pentamethylcyclopentadienyl)samarium complexes has been examined to determine why some routes fail and to develop routes superior to the first synthesis from (C5Me5)2Sm and 1,3,5,7-cyclooctatetraene (COT). (C5Me5)2Sm(THF) fails as a reagent since (C5Me5)3Sm reacts with any THF present to form the ring-opened product (C5Me5)2Sm[O(CH2)4C5Me5](THF). However, (C5Me5)2Sm(OEt2)

  已经研究了导致三（五甲基环戊二烯基）sa络合物的合成化学方法，以确定为什么某些路线失败并开发出优于由（C 5 Me 5）2 Sm和1,3,5,7-环辛酸酯（COT ）进行首次合成的路线）。（C 5 Me 5）2 Sm（THF）不能作为试剂，因为（C 5 Me 5）3 Sm与存在的任何THF反应形成开环产物（C 5 Me 5）2 Sm [O（CH 2）4 C 5 Me 5 ]（THF）。但是，（C 5我5）2 Sm（OEt 2）与COT干净地反应形成（C 5 Me 5）3 Sm和（C 5 Me 5）Sm（C 8 H 8）。一种更有效的合成方法涉及（C 5 Me 5）2 Sm（OEt 2）与（C 5 Me 5）2 Pb的反应，生成> 90％收率的（C 5 Me 5）3 Sm。该路线已用于合成空间上更为拥挤的三（五烷基环戊二烯基）配合物（C 5Me 4 Et）3 Sm，这表明尚未实现此类中空间拥挤的限制。对（C

• Synthesis and Molecular Structure of Bis(pentamethylcyclopentadienyl) Phospholyl- and Arsolylsamarium(III) Complexes: Influence of Steric and Electronic Factors

  The title complexes could be easily synthesized respectively from the following biphospholyls: 2,3,4,5,2 ' ,3 ' ,4 ' ,5 ' -octamethylbi-1,1 ' -phospholyl (1); 3,4,3 ' ,4 ' -tetramethylbi-1,1 ' -phospholyl (2); 2,5,2 ' ,5 ' -tetra-tert-butylbi-1,1 ' -phospholyl (3), and CP*Sm-2 or Cp*Sm-2(Et2O) (Cp* = pentamethylcyclopentadienyl). 3,4,3 ' ,4 ' -Tetramethylbi-1,1 ' -arsolyl (4), a precursor of the new 3,4-dimethylarsolyl ligand, was prepared in three steps from the known 1-chloro-2,5-di(trimethylsilyl)-3,4-dimethylarsole (5). The reaction of 4 with CP*Sm-2 afforded the title complex 12. Although the unsubstituted bi-1,1 ' -phospholyl could be observed by NMR, it decomposed during the isolation, and thus the title complex 13 with the unsubstituted phospholyl was prepared from Cp*Sm-2(Et2O) and the new thallium phospholide 8, synthesized by metathesis of lithium phospholide with thallous ethoxide. Compounds 8-13 were characterized by X-ray crystallography. The solid state structures of complexes 9-13 vary depending on the substitution pattern on the phospholyl ligand. They can be eta (1)- or eta (5)-coordinated monomers (respectively 9 and 12), a mu:eta (1):eta (5)- symmetrical dimer (13), or even unsymmetrical dimers where both the eta (1)- and the mu:eta (1),eta (5)-coordination modes are found (10 and 11). These structures are discussed by taking into account the electronic and steric properties of the phospholyl and arsolyl ligands.
