Аннотация

The activation of yellow arsenic is possible with the silylene [PhC(NtBu)₂SiN(SiMe₃)₂] (1) and the disilene [(Me₃Si)₂N(η¹-Me₅C₅)Si=Si(η¹-Me₅C₅)N(SiMe₃)₂] (3). The reaction of As₄ with 1 leads to the unprecedented As₁₀ cage compound [(LSiN(SiMe₃)₂)₃As₁₀] (2; L=PhC(NtBu)₂) with an As₇ nortricyclane core stabilized by arsasilene moieties containing silicon(II)bis(trimethylsilyl)amide substituents. In contrast, the compound [Cp*{(SiMe₃)₂N}SiAs]₂ (4) containing a butterfly-like diarsadisilabicyclo[1.1.0]butane unit is formed by the reaction of As₄ with the disilene 3. Both compounds were characterized by single-crystal X-ray diffraction analysis, NMR spectroscopy, and mass spectrometry. The reaction outcomes demonstrate the different reaction behavior of yellow arsenic (As₄) compared to white phosphorus (P₄) in the reactions with the corresponding silylenes and disilenes.
