Participants

Conditions

Temperature: 80 °C

Procedure

14.3 g of 3-iodopropyltris(trimethylsiloxy)silane (28), 5.7 g of 3-aminopropyltris(trimethyl-siloxy)silane and 9.6 g of sodium carbonate are added to 50 ml dimethylacetamide and stirred for 15 hours at 80° C. The dimethylacetamide is then evaporated and the residue taken up in methylene chloride. The organic phase is washed with water, dried and evaporated. The product is purified by column chromatography on silica gel to give 7 g of a slightly yellowish oil of formula (30); 1H-NMR (ppm, CDCl3): 2.21 6H t, 1.38 6H txt, 0.28 6H t, 0 81H s.
