A Route to Organyl(trialkoxysilyl)chalcogenides and Dichalcogenides, Bis(trialkoxysilylmethyl)chalcogenides and Dichalcogenides

Reactions of organylchalcogenomagnesium halides RYMgX (in situ) (R = Me, Et, Ph; Y = S, Se, Te; X = Br, I) with (halomethyl)trialkoxysilanes X'CH2Si(OR')3 (X' = Cl, I; R' = Me, Et) at reflux in tetra-hydrofuran and the systems of tetrahydrofuran-acetonitrile 1 :2, and ether-acetonitrile 1:2 are studied. These reactions are shown to lead to formation of mixtures of corresponding organyl(trialkoxysilylmethyl)chalcogenide and -dichalcogenide, bis(trialkoxysilyl methyl)chalcogenide and -dichalcogenide, as well as the contaminants 2,2,6,6-tetraalkoxy-2,6-disila-4-chalcogen-1-oxane, diorganylchalcogenide and -dichalcogenide, and other organic and organosilicon compounds. Composition of the formed mixtures depends considerably on the structure of R, nature of the chalcogen Y (S, Se, Te), and halides X and X' in the initial reagents, and reaction conditions. The most of synthesized and isolated organosilicon chalcogenides are newly obtained compounds.
