Dihalogen-bridged NHC-palladium() dimers: synthesis, characterisation and applications in cross-coupling reactions

A di-iodo-bridged Pd I dimer bearing an N-heterocyclic carbene ligand was made accessible via the reduction of [(IPr)PdI 2 ] 2 in basic methanol solution. The structural features of [(IPr)PdI] 2 were explored by single-crystal X-ray analysis. It was found to be a convenient one-component precatalyst...

Zusammenfassung:A di-iodo-bridged Pd I dimer bearing an N-heterocyclic carbene ligand was made accessible via the reduction of [(IPr)PdI 2 ] 2 in basic methanol solution. The structural features of [(IPr)PdI] 2 were explored by single-crystal X-ray analysis. It was found to be a convenient one-component precatalyst with high activity in Suzuki-Miyaura, Buchwald-Hartwig, and Sonogashira reactions. Diiodo-bridged, dinuclear NHC-Pd I complexes have been synthesised and utilised as one-component pre-catalysts for Suzuki-Miyaura, Buchwald-Hartwig, and Sonogashira reactions.
