  O和钽之间的亚胺基/氧代交换作为通往Os（NAr）2R2和OsO（NAr）R2配合物的途径（NAr = N-2,6-i-Pr2C6H3; R = CH2CMe3，CH2CMe2Ph，CH2SiMe3）并尝试进行诱导。 α-氢提取产生亚炔基配合物

  摘要：

  OsO(2)R(2) (R = CH2-t-Bu, CH(2)CMe(2)Ph) or [OsO2(CH(2)SiMe(3))(2)](n) reacts with 1 or 2 equiv of Ta(NAr)(O-t-Bu)(3) (NAr = N-2,6-i-Pr2C6H3) to form complexes of the type OsO(NAr)R(2) or Os(NAr)(2)R(2). OsO(NAr)(CH2-t-Bu)(2) reacts with 2 equiv of HCl or Me(3)SiI in CH2Cl2 or DME to form Os(NAr)(CH2-t-Bu)(2)Cl-2 or Os(NAr)(CH2-t-Bu)(2)I-2, respectively, or with SiMe(3)X in CH2Cl2 to form green, crystalline Os(NAr)(CH2-t-Bu)(2)(OSiMe(3))(X) (X = Cl, OTf), An X-ray structure of Os(NAr)(CH2-t-Bu)(2)(OSiMe(3))(OTf) showed it to be an approximate square pyramid with a neopentyl group in the apical position. The reaction of OsO(NAr)(CH2-t-Bu)(2) with 2 equiv of trimethylaluminum in pentane yields red trans-Os(NAr)(CH2-t-Bu)(2)(CH3)(2). None of the Os(VI) dineopentyl complexes shows any evidence for controlled alpha-hydrogen abstraction reactions.
