We report here an iron-bisphosphine complex-catalyzed annulation reaction of an arylindium reagent and two alkyne molecules that affords a substituted naphthalene derivative in moderate to good yield. The reaction represents a new example of iron-catalyzed C-C bond forming reactions via C-H bond functionalization. (C) 2012 Elsevier Ltd. All rights reserved.
Iridium-Catalyzed Reaction of Aroyl Chlorides with Internal Alkynes to Produce Substituted Naphthalenes and Anthracenes
dialkylacetylenes as well as diphenylacetylene in the presence of an iridium catalyst accompanied by decarbonylation to produce 1,2,3,4-tetrasubstituted naphthalenes in good yields. Use of 2-naphthoyl chlorides selectively affords the corresponding anthracenederivatives.
