Versuchsvorschrift

A solution of tetra-n-butylammonium permanganate (5.1 g, 14.0 mmol) in anhydrous pyridine (35 mL) was transferred via cannula needle into a solution of the stannane 305 (5.0 g, 14.0 mmol) in anhydrous pyridine (35 mL) at 0° C. under a nitrogen atmosphere. The reaction was stirred for 30 min., then saturated aqueous sodium sulfate (50 mL) was added to quench the reaction. The mixture was then poured into ether and the layers separated. The organic layer was washed with 2N aqueous HCl (6 times with 100 mL), water (2 times) and then brine (2 times). The solution was dried with magnesium sulfate, then filtered and concentrated under vacuum to provide 4.8 g (92% yield) of the stannane 306 as a white solid.
