Abstract

I Enolization of 1 does not occur readily. The compound gives no color with ferric chloride solution and shows no hydroxyl absorption in the infrared. 3 It dissolves in alkali, but acidification yields 2, 4-dichloro-3-phenyl-3-butenoic acid and complex prod~ cts.~ No reaction was noted in an attempt to convert I to 1-acetoxy-2, 4-dichloro-3- phenylcyclobutadiene with isopropenyl acetate in the presence of p-toluenesulfonic acid ...
