9-[6-(Diphenylphosphino)pyridin-2-yl]-9H-carbazole: synthesis and coordination properties toward CuI and PdII

9-[6-(Diphenylphosphino)pyridin-2-yl]-9H-carbazole was synthesized in two steps involving cross-coupling of 2,6-dibromopyridine with carbazole followed by treatment of the formed monobromo pyridine derivative with Ph₂PCl. The coordination properties of the synthesized ligand were demonstrated by the reaction with Pd(COD)Cl₂ and CuI. The alkylation of the title compound with MeI proceeds selectively at the P atom to afford the corresponding phosphonium salt.
