Copper-Free Monomeric and Dendritic Palladium Catalysts for the Sonogashira Reaction: Substituent Effects, Synthetic Applications, and the Recovery and Re-Use of the Catalysts

A series of bis(tert‐butylphosphine)‐ and bis(cyclohexylphosphine)‐functionalized PdII monomers and polyamino (DAB) dendritic catalysts were synthesized and investigated for Sonogashira carbon–carbon coupling reactions in a copper‐free procedure. The influence of phosphine substituents (tBu versus C...
