Versuchsvorschrift

Triphenyl tin hydride was prepared as follows: a 4-neck flask equipped with magnetic stirring was charged with 600 ml of ether and 3.1 g (81 mmol) of LiAlH4 and cooled to 0° (ice+salt bath). 62.6 G (0.16 mol) of triphenyl tin chloride were added by means of a dropping funnel adapted for powder introduction. No exothermic reaction was observed. The mixture was allowed to warm up to room temperature and stirred for 1 h. It was then poured on ice, extracted with ether, washed 3 times with water, dried and concentrated. The raw product thus obtained (56.8 g) was used as such in the synthesis described above.
