Versuchsvorschrift

To a 1 liter autoclave, was added 250 g (1.5 mol) tris(dimethylamino)silane, 100 g xylene, 168 g (3.1 mol) 1,3-butadiene and 200 ppm RhCl(PPh3)3 (0.45 g) as the catalyst. After the autoclave was secured, the reaction was heated to 125° C. for four hours. The reactor was then cooled to room temperature. GC and GC/MS revealed that the major product formed was 1-tris(dimethylamino)silylbuta-1,3-diene in 65% yield. 1-tris(dimethylamino)silylbut-1-ene was also formed in 32% yield.
