実験手順

To a solution of 46.6 g of p-phenylacetophenone in 250 ml. of dimethyl sulfoxide, there is added 65.5 g of lithium acetylide - ethylene diamine complex. After 18 hours at room temperature, the mixture is poured on 2 liters of iced water. The initial oil solidifies on standing, is filtered off and recrystallized from 150 mlof isopropyl alcohol to give 2-(p-biphenylyl)-3-butyn-2-ol, mp 75°-80° C.
