Reactions of titanocene polyselenide complexes with methyldichloroarsane: synthesis and properties of (CH3C5H4)2Ti(μ2-Se2)2AsCH3 and of (CH3As)2Se3

(C5H4CH3)4Ti2Se4 reacts at 0 deg C in CS2 with CH3AsCl2 in a molar ratio of 1:1 to give the novel (C5H4CH3)2TiSe4AsCH3, which forms air-stable black-violet crystals that have been characterized by 1H NMR, mass, and infrared spectra.When a molar ratio of 1:2 is used the novel (CH3As)2Se3 rather than (CH3As)2Se4 is obtained, as orange crystals together with elemental selenium. (CH3As)2Se3 can also be prepared from (C5H4CH3)2TiSe5 and CH3AsCl2 at 20 deg C in CS2; it probably contains five-membered 1,3-As2Se3 rings.
