Yield: 81%
Reaction Conditions:
in diethyl ether;water at 0 - 20;Inert atmosphere;
Steps:
A mixture (400 mL) of diethyl oxide:water 1:1 was cooled at 0° C. under nitrogen in a three-necked flask of 1 L. Sodium borohydride (3 g, 79.4 mmol) and then tricyclohexyltin hydroxide (30 g, 62.2 mmol) were successively and carefully added. After addition of 100 mL of diethyl oxide, the mixture was stirred 2 days at room temperature. After separation, the organic layer was dried over magnesium sulphate and evaporated under reduced pressure. The crude product was distilled under high vacuum to afford, a colourless oil (23.23 g; 63 mmol).Yield: 81%1H NMR (CDCl3) δ: 5.29 (s, 1H); 2.82-1.39 (bs, 33H).13C NMR (CDCl3) δ: 31.56; 27.57; 25.62; 24.37.119Sn NMR (CDCl3) δ: -92.8 ppm.
