Arsenosiloxanes: Formation and Decomposition of Trialkylsilyl Arsenates und Arsenites

Tris(trialkylsilyl) arsenates(V) are prepared from silver arsenate(V) and chlorotrialkylsilanes or from arsenic acid and hexaalkyldisilazanes.The triethylsilyl ester 1b is stable, but the trimethylsilyl ester 1a undergoes condensation at ambient temperature to give hexamethyldisiloxane and trimethylsilyl polyarsenates(V), including tetrakis(trimethylsilyl) diarsenate(V) (4a).According to an X-ray crystal structure determination of 4a (triclinic, space group P1) centrosymmetrical dimers are present containing two edge-sharing AsO6 octahedra with apex-bridging by two AsO4 tetrahedra. 1a is converted into the salt + CF3SO3-, the cation of which is believed to be a component of the reaction chain.There is also evidence by mass spectrometry for the existence of (Me3SiO)5As (5). - Tris(trimethylsilyl) arsenite(III) (6) is prepared from AsCl3 and NaOSiMe3.With modified stoichiometry, side reactions give also the byproducts Cl2AsOSiMe3, ClAs(OSiMe3)2, Cl2AsOAsCl2, Cl2AsOAsCl(OSiMe3), O2, and cyclic chloroarsenosiloxanes (12, 13).
