Versuchsvorschrift

Tin powder (100 g) and 2-chloroanthraquinone (70 g) were refluxed in acetic acid (500 ml) while concentrated hydrochloric acid (130 ml) was added over a period of 3 hours. The solution was cooled and the product was separated by filtration, and then chromatographed on silica gel, eluting with benzene:ether, so as to afford 2-chloroanthrone and 3-chloroanthrone.
