Versuchsvorschrift

A mixture of 15.5 g. of 2-vinylnaphthalene, 23 g. of diiodomethane, 19.6 g. of zinc-copper couple (comprising 19.5 g. of zinc and 0.1 g. of copper) and 500 ml. of diethyl ether is refluxed for eight hours; the cooled mixture is then filtered, washed with dilute hydrochloric acid, washed with water to neutrality, dried and evaporated to yield 2-cyclopropylnaphthalene.
