Reaktionsschritte
Under a nitrogen atmosphere, 101.3 g (0.50 mole) of 3-chloro-2-methylbiphenyl (92% purity) in 75 g of dry tetrahydrofuran was added dropwise over two hours with stirring to a gently refluxing mixture of 13.1 g (0.54 mole) of fresh magnesium turnings, the heel from a previous run containing 0.21 mole of unreacted magnesium, and 75 g of dry tetrahydrofuran in a dry reaction vessel. Upon complete addition, the reaction mixture was heated at reflux for five additional hours. Gas chromatographic analysis of a quenched sample of the reaction mixture showed 1.2% of unreacted 3-chloro-2-methylbiphenyl and 92.4% of 2-methylbiphenyl. The reaction mixture was allowed to cool overnight.
