Hydrochloric Acid → Benzyl 2,4-dihydroxyphenyl ketone

Participants

Reaction Steps

The 2,4-dihydroxyphenol benzyl ketone was prepared by treating a mixture of 100 parts of resorcinol, 100 parts of benzyl cyanide and 20 parts of anhydrous zinc chloride in dry ether with hydrogen chloride gas saturated. After standing for 2 days the lower oily layer was separated off, washed with ether by decantation and boiled with 200 parts of water for 2 hours. After cooling the yellow crystals were collected by filtrate and dried. Crystallisation from benzene gave 2,4-dihydroxyphenyl benzyl ketone as yellow/orange crystals, melting at 113°-114° C.
