Specification

The Palladium diacetate, with the CAS registry number 3375-31-3 and EINECS registry number 222-164-4, has the systematic name and IUPAC name of palladium(2+) diacetate. The molecular formula of this chemical is C₄H₈O₄Pd. It is a brown needles which is hygroscopic, and insoluble in water.

The Palladium diacetate is a catalyst for many organic reactions by combining with many common classes of organic compounds such as alkenes, dienes, and alkyl, aryl, and vinyl halides to form reactive adducts. It is also used as oxidizer in some organic synthesis.

The physical properties of Palladium diacetate are as following: (1)ACD/LogP: -0.29; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -1.07; (4)ACD/LogD (pH 7.4): -2.86; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)ACD/KOC (pH 5.5): 2.73; (8)ACD/KOC (pH 7.4): 1; (9)#H bond acceptors: 2; (10)#H bond donors: 1; (11)#Freely Rotating Bonds: 0; (12)Polar Surface Area: 37.3 Å²; (13)Flash Point: 40 °C; (14)Enthalpy of Vaporization: 23.7 kJ/mol; (15)Boiling Point: 117.1 °C at 760 mmHg; (16)Vapour Pressure: 13.9 mmHg at 25°C.

Preparation of Palladium diacetate: Add 10g spongy palladium to the 250ml glacial acetic acid and 9ml concentrated nitric acid solution, and relux it with heat. Filter the brown solution, and cool it down, you can get the orange brown crystals. Wash it with acetic acid and water, and dry in the air. Dissolve it with hot benzene, and add half volume of glacial acetic acid. The benzene will evaporate, and left large crystalline product.
Pd+HNO₃+2CH₃COOH→Pd(OCOCH₃)₂+2NO₂+2H₂O

Uses of Palladium diacetate: It can be used to produce other palladium(II) compounds. For example, phenylpalladium acetate, used to isomerize allylic alcohols to aldehydes, is prepared by the following reaction:
Hg(C₆H₅)(CH₃COO) + Pd(CH₃COO)₂ → Pd(C₆H₅)(O₂CCH₃) + Hg(O₂CCH₃)₂

You should be cautious while dealing with this chemical. It irritates eyes, respiratory system and skin. There's limited evidence of a carcinogenic effect about this chemical, and it has risk of serious damage to eyes. Therefore, you had better take the following instructions: Wear suitable protective clothing, gloves and eye/face protection, and in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice.

You can still convert the following datas into molecular structure:
(1)SMILES: [Pd+2].[O-]C(=O)C.[O-]C(=O)C
(2)InChI: InChI=1/2C2H4O2.Pd/c2*1-2(3)4;/h2*1H3,(H,3,4);/q;;+2/p-2
