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 tetrahydrofuran 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(trialkoxysityl methyl)chalcogenide and -dichalcogenide, as well as the contaminants 2,2,6,6-tetraalkoxy-2,6-disila-4-chalcogen-l-oxane, diorganylchalcogenide and -dichalcogenide, Zn and other organic and organosilicon compounds. Composition of the formed mixtures debends considerably on the structure of R, nature of the chalcogen Y (S, Se, Te), and halides X and X' in the initial reagents, and T reaction conditions. The most of synthesized and isolated organosilicon chalcogenides are newly obtained compounds.
