The synthesis of palladium cyclometallated compounds with thiosemicarbazone ligands is described,as well as their reactivity with bidentate phosphine ligands. The synthesis of the ligands is carried out by a condensation reaction between a ketone and a thiosemicarbazide. Subsequently, metallation proceeds, and the resulting product is reacted with the bis(diphenylphosphino)methane (dppm) using the appropriate conditions to obtain the compound with phosphine in a monodentate coordination mode.
