Versuchsvorschrift

The Grignard reagent from t-butyl chloride (92.5 g., 1 mole), magnesium (24.3 g., 1 mole) and tetrahydrofuran (11.) was added dropwise to a solution of tin(iv) chloride (104 g., 0.4 mole) in heptane (11.). A vigorous reaction started at once and magnesium chloride precipitated. After completion of the addition, the mixture was refluxed for 4 hrs. Cooling and work-up gave a yellow oil. This was distilled to give the desired product as a clear oil which solidified readily (70.0 g., 58%), m.p. 42°-43° (lit., 142°); b.p. 66°/3 mm.; n.m.4. 81.45(s).
