Abstract
Fluorine-containing dimethylchlorosilanes are prepared by reacting an ethylene compound having a fluorine-containing organic group with dimethylchlorosilane in the presence of a rhodium complex, for instance RhCl(PPh.sub.3) (Ph: phenyl group), as a catalyst. The use of a rhodium complex as a catalyst enables preparation in high yield of the fluorine-containing dimethylchlorosilane, which has been heretofore obtainable only in low yields.
