Versuchsvorschrift

Adam's catalyst (0.2 g) was added to a solution of 1-(2-cyclohexen-1-yl)-2,2,2-trichloroethanol (23 g) in methanol (220 ml) and this mixture was stirred under a slight positive pressure of hydrogen. Uptake of hydrogen was complete after 400 minutes and the solution was then filtered. The filtrate was evaporated to give 1-cyclohexyl-2,2,2-trichloroethanol of 90% purity as judged by G.L.C. An attempt to purify this material by distillation through a spinning band column gave material of only 85% purity due, presumably, to decomposition brought about by prolonged heating. This material was used without further treatment.
