反应实例
Phenol (4). An ice-cooled 2 (9.1 g, 50 mmol) in THF (110 mL) was treated with n-BuLi (1.24M, 45 mL). 1 (5.8 g, 53 mmol) was added and the red solution was refluxed for 4 h. Evaporation, addition of Et2O, water and distillation afforded 8.5 g of 5 (87%), bp 87–90 C/0.2 mmfrom Et2O, and 3.81 g of 4 (83%) from the aq layer.
