Abstract

A series of new 6-and 7-membered N-heterocyclic carbene (NHC) complexes of palladium (NHC) Pd (cinn) Cl (cinn= cinnamyl= 3-phenylallyl) were synthesized and characterized structurally in the solid state. The influence of ring size (5, 6 or 7) and bulkiness of N-aryl substituents (Mes= 2, 4, 6-trimethylphenyl, or Dipp= 2, 6-diisopropylphenyl) in carbenes on palladium catalysed Suzuki–Miyaura cross-coupling was revealed. Due to the unique ...
