Abstract
Acylation of 1-acetoxy-2-phenoxyethane with phenylacetyl chloride in the presence of anhydrous aluminium chloride or tin tetrachloride afforded 1-acetoxy-2-(4-phenylacetylphenoxy)ethane (I) as the principal product. In the presence of aluminium chloride 1-[4-(2-acetoxyethoxyphenyl)]-1-chloro-2-phenylethene (II), 1,1-di-[4-(2-acetoxyethoxyphenyl)]-2-phenylethene (III) and 1-[4-(2-hydroxyethoxyphenyl)]-1-chloro-2-phenylethene (IV) were isolated as side-products whereas in the tin tetrachloride-catalyzed reaction only III was detected.
