Versuchsvorschrift

A Grignard reagent was prepared from 100 ml of THF, magnesium (120 mmole) and trans-1-pentyl-4-(trans-4-chloromethylcyclohexyl)cyclohexane (100 mmole) under nitrogen atmosphere. A THF 100 ml solution of tetramethoxysilane (150 mmole) was heated to 65° C., and the Grignard reagent was added dropwise thereto. Further, the solution was stirred at the same temperature for 2 hours, and after left standing for cooling, the reaction mixture was filtered. The solvent was distilled off, and then trans-1-pentyl-4-(trans-4-trimethoxysilylmethyl-cyclohexyl)cyclohexane (65 mmole) was obtained by distillation under reduced pressure.
