Versuchsvorschrift

To a solution of 16.8 g 10-undecenal in 25 ml methylene chloride, crystals of di-μ-chlorodichlorobis(ethylene)-diplatinum (II) were added and the solution heated to 40°-45° C. A solution of 16.4 g triethoxysilane in 25 ml methylene chloride was added dropwise over a period of 90 minutes. After reagent addition was completed, the rection mixture was heated for an additional 30 minutes. The mixture was fractionated and the product, 11-triethoxysilylundecanal (I) was obtained at 65° C. at 0.2 mm Hg at a 30% yield.
