実験手順

A solution of 115 ml of 2.7 N butylmagnesium bromide in diethyl ether was added in about one hour to a solution of 62.5 g (0.15 mol) of (3-bromopropyl)methyltin dibromide in 200 ml of diethyl ether. After reflux for 1 h the mixture was treated with a saturated aqueous solution of NH4Cl and distilled to give 48.79 g (88%) of (3-bromopropyl)methyldibutyltin; b.p. 88°-90° C./0.1 mm Hg, nD20 =1.5001.
