Copper(i)-catalyzed homo-coupling of terminal alkynes at room temperature under solvent and base free conditions using O2 as an oxidant

Author affiliations

Abstract

The homo-coupling of various terminal alkynes were realized in the presence of 0.5 mol% CuI and 5 mol% benzylamine. This transformation proceeded at room temperature under solvent and base free conditions using O2 as an oxidant. The TON was up to 1760.
