FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention describes a method for preparing alkylsilanes that involves the hydrosilylation reaction of gaseous unsaturated hydrocarbon with silane hydride in the presence of chloroplatinic acid solution as a catalyst in an organic solvent with an additive. As an addition the method involves using tetramethyldivinyl disiloxane or hexavinyl disiloxane in the volume ratio of chloroplatinic acid solution to the additive = 1:(0.5-2), respectively. Invention provides the development of a method providing preparing the broad spectrum of alkylsilanes with high yield of product, simplifying the synthesis process and diminishing time for its realization.
EFFECT: improved preparing method.
