Homoleptic Selenolates of Vanadium(II), -(III), and -(IV): Generation, Trapping, and Disproportionation of Tris[tris(trimethylsilyl)silylselenolate]vanadium

Homoleptic selenolates of V(II) and V(IV) are prepared by selenolysis ofthe amide ligands in [(Me3Si)2N]2VSeSi(SiMe3)3 with 2 equiv of HSeSi(Si Me3)3. The products were isolated by fractional crystallization from a mixture of hexanes/HMDSO (HMDSO = hexamethyldisiloxane), which first gavea V(II) selenolate of empirical composition V[SeSi(SiMe3)3]2(HMDSO)1/2, followed by the more soluble monomeric V(IV) species, V[SeSi(SiMe3)3]4. These compounds are proposed to be the disproportionates of a V(III) pr ecursor (i.e. V[SeSi(SiMe3)3]3 ). Room-temperature EPR spectra of the tetraselenolate exhibited an 8-line pattern typical of V(IV) with g(iso) = 1.92 and A(iso) = 65 G. Addition of 2 equiv of DMPE (DMPE = 1,2-bis(dimethylphosphino)ethane) to the V(II) selenolate afforded trans-(DMPE)2V[SeSi(SiMe3)3]2 which has been characterized by X-ray crystallography. V[SeSi(SiMe3)3]3 can be generated in cold hexanes and trapped with Lewisbases to afford the 4-coordinate adducts V[SeSi(SiMe3)3]3(L) (L = pyrid ine, 2,6-dimethylphenylisocyanide). For L = pyridine, addition of styrene oxide resulted in a 2-electron oxidation and formation of diamagnetic OV[SeSi(SiMe3)3]3. Reaction of 1/2 equiv of pyrazine with V[SeSi(SiMe3)3]3 gave the pyrazine-bridged dimer {V[SeSi(SiMe3)3]3}2(μ-pyrazine) which was also crystallographically characterized.
