Palladium-catalyzed reaction of o-alkynyltrifluoroacetanilides with 1-bromoalkynes. An approach to 2-substituted 3-alkynylindoles and 2-substituted 3-acylindoles

The palladium-catalyzed reaction of o-alkynyltrifluoroacetanilides with 1-bromoalkynes affords free N-H 2-substituted 3-alkynylindoles in satisfactory to high yield. 2-Substituted 3-alkynylindoles revealed useful intermediates for the regioselective synthesis of 2-substituted 3-acylindoles. The latter can be prepared from o-alkynyltrifluoroacetanilides and 1-bromoalkynes via a one-pot cyclization-hydration protocol, omitting the isolation of 2-substituted 3-alkynylindoles.

Carbocatalytic Oxidative Dehydrogenative Couplings of (Hetero)Aryls by Oxidized Multi-Walled Carbon Nanotubes in Liquid Phase

HNO3-oxidized carbon nanotubes catalyze oxidative dehydrogenative (ODH) carbon–carbon bond formation between electron-rich (hetero)aryls with O2 as a terminal oxidant. The recyclable carbocatalytic method provides a convenient and an operationally easy synthetic protocol for accessing various benzofused homodimers, biaryls, triphenylenes, and related benzofused heteroaryls that are highly useful frameworks for material chemistry applications. Carbonyls/quinones are the catalytically active site of the carbocatalyst as indicated by model compounds and titration experiments. Further investigations of the reaction mechanism with a combination of experimental and DFT methods support the competing nature of acid-catalyzed and radical cationic ODHs, and indicate that both mechanisms operate with the current material.

Cycloisomerization of 2-alkynylanilines to indoles catalyzed by carbon-supported gold nanoparticles and subsequent homocoupling to 3,3′-biindoles

Elevated by the support: 2-Alkynyl aniline cycloisomerization to indole is catalyzed by cationic Au NPs on a carbon support. Electroneutral and rich 2-aryl indoles are further converted into 3,3′-biindoles by oxidative homocoupling that is readily catalyzed by the Au NPs on carbon, and exclusively but also somewhat sluggishly by the carbon support.
