Key words

palladium nanoparticles - imidazolium iodide - Heck reaction - Sonogashira coupling - Hiyama coupling

Significance

Palladium nanoparticles 1 stabilized by tris-imidazolium iodide catalyzed the Heck ­reaction (eq. 1), the copper-free Sonogashira coupling (eq. 2), and the fluoride-free Hiyama coupling (eq. 3).
