Versuchsvorschrift
A mixture of 61 grams of methyloctylsilane and 186 grams of 1-octene was reacted in the presence of 0.0075 gram of chlorotris(triphenylphosphine)rhodium(I) for 2.5 hours at 85°-89° C. Analysis by GLC showed a total of 15 percent of unsaturated product. After removing unreacted octene by stripping, the residue was hydrogenated as in Example 1. Distillation revealed an 86 percent yield of methyltri(octyl)silane having a boiling point of 188°-189° C. (0.9 mm).
