A straightforward synthesis method for mixed phosphane dipyrido‐annelated N‐heterocyclic carbene (dipiy) palladium(II) complexes is presented. The key step is the oxidative addition of 6‐bromodipyridoimidazolium bromides that can be prepared easily from dipyridine in a two step reaction. This new procedure avoids any generation of the free carbene as well as any transmetallation step.
The straightforward synthesis of mixed dipyrido NHC‐phosphane PdII complexes by the oxidative addition of 6‐bromodipyridoimidazolium salts is presented. This procedure avoids any transmetallation step orformation of a free carbene. Synthesis of the brominated starting material can easily be achieved by reaction of the corresponding imidazolium or benzoylimidazolium salt with bromine.
