Versuchsvorschrift

15 ml of 2,4,4-trimethyl-pentene-1 are dissolved in 150 ml of CH2Cl2, cooled to -30° C. and mixed dropwise with a mixture of 10.3 ml of thionyl chloride and 5.4 ml of H2O. The mixture is then heated to 0° C. and washed after 2.5 hours with cold 1% aqueous K2CO3 solution, then with ice-cold water. The product is dried over MgSO4 and distilled off. Yield 85%; nD20 =1.4308; Bpt.10 mm 38° C.
