METHOD OF PRODUCING ALKYL SILANES Russian patent published in 2011 - IPC C07F7/08 

FIELD: chemistry.

SUBSTANCE: in order to simplify the process of producing alkyl silanes and their further purification, synthesis of alkylchloro silanes is carried out in the medium of aromatic hydrocarbons in the presence of a catalyst - tetrakis(diethylamido)-phosphonium salts, more preferably bromides and chlorides, at temperature ranging from 20°C to 250°C. The activator is used in amount of 0.005-1 mol, more preferably 0.01-0.05 mol for each substituted halogen atom in the initial alkylchloro silane.

EFFECT: disclosed method enables to obtain the end product with high purity and high output.
