Different Reactivity of As₄towards Disilenes and Silylenes

The activation of yellow arsenic is possible with the silylene [PhC(NtBu) SiN(SiMe ) ] (1) and the disilene [(Me Si) N(η -Me C )Si=Si(η -Me C )N(SiMe ) ] (3). The reaction of As with 1 leads to the unprecedented As cage compound [(LSiN(SiMe ) ) As ] (2; L=PhC(NtBu) ) with an As nortricyclane core stabilized by arsasilene moieties containing silicon(II)bis(trimethylsilyl)amide substituents. In contrast, the compound [Cp*{(SiMe ) N}SiAs] (4) containing a butterfly-like diarsadisilabicyclo[1.1.0]butane unit is formed by the reaction of As 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 (As ) compared to white phosphorus (P ) in the reactions with the corresponding silylenes and disilenes.

Cp^PEt₂As₄—An Organic‐Substituted As₄ Butterfly Compound

Cp As (Cp =C (4-EtC H ) ) (1) is synthesized by the reaction of Cp radicals with yellow arsenic (As ). In solution an equilibrium of the starting materials and the product is found. However, 1 can be isolated and stored in the solid state without decomposition. As can be easily released from 1 under thermal or photochemical conditions. From powder samples of Cp As , yellow arsenic can be sublimed under rather mild conditions (T=125 °C). A similar behavior for the P -releasing agent was determined for the related phosphorus compound Cp P (2; Cp =C (4-nBuC H ) ). DFT calculations show the importance of dispersion forces for the stability of the products.

CpPEt2As4 (CpPEt=C5(4‐EtC6H4)5) (1) is synthesized by the reaction of CpPEt. radicals with yellow arsenic (As4). In solution an equilibrium of the starting materials and the product is found. However, 1 can be isolated and stored in the solid state without decomposition. As4 can be easily released from 1 under thermal or photochemical conditions. From powder samples of CpPEt2As4, yellow arsenic can be sublimed under rather mild conditions (T=125 °C). A similar behavior for the P4‐releasing agent was determined for the related phosphorus compound CpBIG2P4 (2; CpBIG=C5(4‐nBuC6H4)5).
