Abstract (en)

[origin: WO2011051133A1] The invention relates to a process for preparing diorganyldihalosilanes of the general formula (1) R2SiX2 (1), in which dihalodihydrosilanes of the general formula (2) X2SiH2 (2), in a mixture with silanes of the general formula (3) R'3SiH (3), are reacted with halogenated hydrocarbons of the general formula (4) R-X (4), in the presence of a free-radical initiator, which is selected from alkanes, diazenes and organodisilanes, where R is a monovalent C1-C18 hydrocarbon radical, R' is a monovalent C1-C18 hydrocarbon radical, hydrogen or halogen, and X is halogen.
