Template-controlled Sonogashira cross-coupling reactions on a Au(111) surface†
Abstract
We employed three metal-coordination structures as templates to control the Sonogashira cross-coupling reactions on a Au(111) surface catalyzed by loaded Pd. We used scanning tunnelling microscopy to resolve the products formed at the successive reaction steps and identified three vital characteristics for an efficient template: high accessibility of reaction sites, structural rigidity and thermal stability.
