摘要

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 l-methyl-l-phenyl-3- chloroindene. The reactions proceeded via the corresponding HCl diadducts, Le., via l-aryl- 1, l-dichloroethanes as intermediates.
