Abstract
A one-step process for the preparation of organodisilanes. The process comprises contacting magnesium metal with a mixture comprising diethylene glycol dibutyl ether, an organic halide, and a halodisilane at a temperature within a range of about 0.degree. C. to 250.degree. C. The process provides a high yield of organodisilane product that is easily recoverable. The present process is especially useful for converting halodisilanes in a high-boiling mixture resulting from the direct process for making organosilane monomers into hexaorganodisilanes.
