Versuchsvorschrift

A mixture of 1-phenyl-1-propanol (0.16 g, 1.17 mmol) and Catalyst A or B (30 mg) in toluene (1 ml) was stirred and heated at 75° C. for 10 h under nitrogen. Ether (20 ml) was added and the mixture was filtered to remove the catalyst. The organic washings were concentrated under reduced pressure at room temperature to afford β-methyl styrene as a colourless oil (0.13 g, 92%).
