tert‐Butoxyacetylene is shown to undergo Sonogashira coupling with aryliodides to yield aryl‐substituted tert‐butyl ynol ethers. These intermediates participate in a [1,5]‐hydride shift, which results in the extrusion of isobutylene and the generation of aryl ketenes. The ketenes are trapped in situ with multiple nucleophiles or undergo electrocyclic ring closure to yield hydroxynaphthalenes and quinolines

The unusual intramolecular arene/allene cycloaddition described 30 years ago by Himbert permits rapid access to strained polycyclic compounds that offer great potential for the synthesis of complex scaffolds. To more fully understand the mechanism of this cycloaddition reaction, and to guide efforts to extend its scope to new substrates, quantum mechanical computational methods were employed in concert

A facile synthetic protocol for the preparation of tertiary amides has been developed. The title compounds have been successfully obtained by the Pd-catalyzed cross-coupling reactions of readily available aryl and benzyl organozinc reagents with the appropriate carbamoyl chlorides.
