p-Toluenesulfonic acid → HCID 178506636, compound

Participants

Reaction Steps

A solution of 7 g of 1-(4-t-butylphenyl)cyclopent-2-en-1-ol (0.032 mole) and 0.1 g of p-toluenesulphonic acid (0.00058 mole) in 70 ml toluene was gently heated to 40° C. for 5 minutes. The mixture was washed with aqueous sodium hydroxide and subsequently with water. After drying the organic phase over magnesium sulphate for 2 hours, 20.3 ml of a solution of n-butyllithium in hexane (1.6 mole/liter, 0.032 mole n-butyllithium) was added. A precipitate was formed and the precipitate was washed three times with hexane to obtain 4-t-butylphenylcyclopentadienyllithium as an off-white solid material.
