Method for the synthesis of silanes or organosilicon hydrides by the reduction of the corresponding silicon halides or organosilicon halides

摘要

A method for the synthesis of silanes or organosilicon hydrides by the reduction of the corresponding silicon halides or organosilicon halides with a magnesium hydride in a liquid reaction medium is carried out by utilizing the following distinguishing features: a) the use of non-pyrophoric, preferably autocatalytically produced, storage magnesium hydride as magnesium hydride, b) the use of conventional ethers as reaction medium, and c) the continuous removal of the magnesium halide formed being deposited on the surface of the magnesium hydride particles during the reaction by the action of mechanical energy or ultrasound so as to form a fresh surface.
