  Synthesis and Characterization of Group 13 and 15 Selenolates and Tellurolates and the x-ray Crystal Structures of Ga[TeSi(SiMe3)3]3, In[SeC(SiMe3)3]3, {In[SeSi(SiMe3)3]3}2(.mu.-DMPE), and P[SeSi(SiMe3)3]3

  摘要：

  A broad range of chalcogenolate complexes of group 13 and 15 elements have been isolated and studied. Metathesis of AlEt(2)Cl with (THF)LiSeSi(SiMe(3))(3) gave (THF)AlEt(2)[SeSi(SiMe(3))(3)] in good yield. Chalcogenolysis of Al[N(SiMe(3))(2)](3) With 3 equiv of HESi(SiMe(3))(3) (E = Se, Te) afforded Al[ESi(SiMe(3))(3)](3) (E = Se, Te). Treatment of GaCl3 with 3 equiv of (THF)(2)LiTeSi(SiMe(3))3 produced the homoleptic species Ga[TeSi(SiMe(3))(3)](3); likewise, addition of 3 equiv of (DME)LiSeC(SiMe(3))(3) to InCl3 yielded In[SeC(SiMe(3))(3)](3). Reaction of InCl3 with 3 equiv of (THF)(2)-LiSeSi(SiMe(3))(3) produced (THF)In[SeSi(SiMe(3))(3)](3) in low yield. Homoleptic chalcogenolates, In[ESi(SiMe(3))(3)](3) (E = Se, Te) were prepared by chalcogenolysis of InCp(3) (Cp = eta(5)-C5H5). Addition of THF, pyridine, or TMEDA (N,N,N',N'-tetramethylethylenediamine) to In[SeSi(SiMe(3))(3)](3) gave 1:1 adducts, (L)In[SeSi(SiMe(3))(3)](3) (L = THF, pyridine, TMEDA). Addition of DMPE (1,2-bis(dimethylphosphino)ethane) to In[SeSi(SiMe(3))(3)](3), produced a 1:1 complex In[SeSi(SiMe(3))(3)](3)(DMPE) that was characterized in solution by NMR spectroscopy; attempts to isolate the complex yielded instead the crystalline 2:1 adduct {In [SeSi(SiMe(3))(3)](3)}(2)(u-DMPE), whose X-ray structure was determined. Indium(I) complexes InESi(SiMe(3))3 (E = Se, Te) were isolated from either the metathesis of InCl with (THF)(2)LiESi(SiMe(3))3 or chalcogenolysis with InCp. Likewise, chalcogenolysis with TlCp produced TlESi(SiMe(3))3 (E = Se, Te). Reaction of PCl3 with (THF)(2)LiSeSi(SiMe(3))(3) produced P[SeSi(SiMe(3))(3)](3) in good yield. The arsenic derivative As[SeSi(SiMe(3))(3)](3) was isolated from the reaction of As(NMe(2))3 and 3 equiv of selenol. Similarly, the antimony and bismuth complexes M[ESi(SiMe(3))(3)](3) (M = Sbt E = Se, Te; M = Bi, E = Se, Te) were prepared in good yields by chalcogenolysis with Sb(NMe(2))3 or Bi[N(SiMe(3))(2)](3).
