Versuchsvorschrift

9.1 g of the triphenyltin hydride (0.026 mol), prepared in the aforementioned example (1), 2.8 g of acrylonitrile (0.052 mol), 85 mg of 2,2'-azobisisobutyronitrile, and 25 ml of toluene were mixed together in a 100 ml four-neck flask equipped with a stirrer and reflux condenser, and stirred while heating for 6 hours at 60° C. After it was confirmed by means of an IR spectrum that the absorption of Sn-H bonds had completely disappeared, a crystal precipitate was separated by filtration. The filtrate was then concentrated under reduced pressure to yield 10.5 g of the final product of 3-(triphenylstannyl)propionitrile (yield=100%).
