  Syntheses and structures of [Me2Si{As(PtBu)3}2] and [(CyP)3SiMe2] (Cy=cyclohexyl, C6H11)

  摘要：

  The reaction of the anion [((BuP)-Bu-t)(3)As] (1) with Me2SiCl2 results in nucleophilic substitution of the Cl- anions, giving the di- and mono-substituted products [Me2Si{As(PtBu)(3)}(2)] (3a) and [Me2Si(Cl){As((PBu)-Bu-t)(3)}] (3b). Analogous reactions of the pre-isolated [(CyP)(4)As](-) anion (2) (Cy = cyclohexyl) with Me2SiCl2 produced mixtures of products, from which no pure materials could be isolated. However, reaction of 2 [generated in situ from CyPHLi and As(NMe2)(3)] gives the heterocycle [(CyP)(3)SiMe2] ( 4). The X-ray structures of 3a and 4 are reported. (C) 2009 Elsevier B. V.
