Direct and Improved Access to Unsymmetrically Functionalized Bipyridines by a Stille-Type Cross-Coupling Reaction

Abstract

The Stille-type cross-coupling reaction on mesylate, tosylate, and triflate allowed synthesis of symmetrical but also interesting unsymmetrical monofunctionalized 2′2′-bipyridines in possible multigram scales.

Keywords:

• Stille-type reaction
• Bipyridines multigram scale synthesis
