Liquid-phase reactions of anhydrous hydrogen chloride with p-methyl-, p-methoxy-, p-fluoro-, and unsubstituted phenylacetylene afforded cyclic trimers, tetramers, and pentamers of the corresponding arylacetylenes.Phenylacetylene gave additionally 1-methyl-1-phenyl-3-chloroindene.The reactions proceeded via the corresponding HCl diadducts, i.e., via 1-aryl-1,1-dichloroethanes as intermediates.
