Freedom: a copper-free, oxidant-free and solvent-free palladium catalysed homocoupling reaction†
Abstract
Herein, we describe a copper-free, oxidant-free, solvent-free homocoupling reaction using a palladium catalyst under mechanochemical conditions. We extended the methodology to palladium catalyst on solid support which showed a different reactivity and different product ratios from the non-supported catalyst. We were able to recycle the polymer supported catalyst for 5 cycles.
