  Stibasilene Sb═Si and Its Lighter Homologues: A Comparative Study

  摘要：

  The multiply bonded derivatives of the heavier main group elements are among the most challenging targets for synthetic pursuits. Those of them featuring a double bond between the silicon and group 15 element are represented mostly by the silaimines -N=Si< and phosphasilenes -P=Si< with a very few examples of arsasilenes -As=Si<. In this contribution, we report on the synthesis and structural elucidation of the first stable stibasilene and novel phosphasilene and arsasilene derivatives, featuring an identical substitution pattern. A systematic comparison within the series phosphasilene-arsasilene-stibasilene is made on the basis of their experimental and computational studies.

  synthesized in excellent yields from the difluoroarsine ArAsF2 by reaction with ArAs(Li)SiMe3 (for 1) and with ArP(H)Li followed by t-BuLi (for 6). Compound 1, previously prepared by other routes, as well as the new compound 6 were characterized by single-crystal X-ray diffraction (d(AsAs) 2.2634(3) Å, d(PAs) 2.141(5) Å).

  The first compound featuring an AsGe double bond, arsagermene Mes*AsGe(SiMetBu2)2, was synthesized, isolated and fully characterized. Crystallographic studies revealed that arsagermene has a planar GeAs bond of 2.2731(8) Å, which is notably shorter than the standard Ge–As single bond. The double bond character of arsagermene was further supported by computational data.
