実験手順

The conventional preparation process of hydroxyphenyl-acetylene has been reported, for example, in Izv. Akad. Nauk SSSR Se. r. Khim 1964(11), 2073-4. In the process, 4-hydroxyacetophenone is chlorinated with phosphorus pentachloride, reacted in liquid ammonia in the presence of metallic sodium and ammonium chloride, and successively treated with water to obtain 4-hydroxyphenylacetylene in 46% yield.
