Versuchsvorschrift

NBS (2.14 g, 12 mmol) and AgNO3 (170 mg, 1 mmol) were added to a solution of triisopropylsilylacetylene (2.24 ml, 10 mmol) in acetone (15 ml). The solution was stirred for 2 hours at RT. Pentane (20 ml) and H2O (20 ml) were added and the solution was stirred for 30 minutes. The organic phase was extracted with pentane (3×20 ml) and dried over Na2SO4. The solvent was removed under reduced pressure at RT and the residue was used in the next reaction without any purification.
