| | Chemical Properties | brown needles | | Uses | suzuki reaction | | Uses | Palladium (II) Acetate Trimer is used in Suzuki-Miyaura cross-coupling reactions. It also serves to catalyze the chemoselective reduction of nitroarenes. | | Uses | A catalyst for intramolecular coupling. | | General Description | Palladium(II) acetate is a homogenous oxidation catalyst. It participates in the activation of alkenic and aromatic compounds towards oxidative inter- and intramolecular nucleophilic reactions. Crystals of palladium(II) acetate have a trimeric structure, having symmetry D3h. Each of the palladium atoms in the crystals are joined to the other two by double acetate bridges. Microencapsulation of palladium(II) acetate in polyurea affords polyurea-encapsulated palladium(II) acetate. It is a versatile heterogeneous catalyst for various phosphine-free cross-coupling reactions. It participates as catalyst in the Heck coupling reaction of pthalides with different alkenes. | | Flammability and Explosibility | Nonflammable | | Safety Profile | Moderately toxic by ingestion. When heated to decomposition it emits toxic vapors of palladium. | | Purification Methods | It recrystallises from CHCl3 as purple crystals. It can be washed with AcOH and H2O and dried in air. Large crystals are obtained by dissolving it in *C6H6, adding half its volume of AcOH and allowing it to evaporate slowly at room temperature. It forms green adducts with nitrogen donors, it dissolves in KI solution to form solid PdI2 and a red solution of PdI42-, but is insoluble in aqueous saturated NaCl, and NaOAc. It dissolves in HCl to form PdCl42-. It is soluble in CHCl3, CH2Cl2, Me2CO, MeCN, Et2O, but it is insoluble in H2O, and decomposes when warmed in alcohols in which it is also insoluble.
