“…Pd-N3-pic bond length is 2.025(2) Å, this value is closer to the value in [Pd(phen)(L)2][PF6]2 (L: 2.030(4) Å for pyridine; L: 2.021(6) -2.016(6) Å for 2picoline) (Chen et al, 1997) and [Pd(3picoline)4]Cl2.2H2O (2.024 (2) Å) (Hallıgudı et al, 1996). But Pd-N3-pic bond length is longer than [Pd(acetato)2(3-pic)2] (2.011(3) Å) (Tessier and Rochon, 1999).…”

A novel palladium(II) complex with 3-picoline and diclofenac ligands was synthesized using [PdCl2(3-pic)2] as the precursor. The synthesized complex is characterized by elemental and thermal and spectroscopic methods. Single X-Ray analysis confirms that the complex has square plane geometry and the compound of formula is [Pd(dicl)2(3-pic)2]. Electronic properties of the complex have been probed by natural bond orbital (NBO) population analyses. Furthermore, relative stabilities of the complexes have been also compared in theoretical insight based on DFT computations since complex [PdCl2(3-pic)2] is the precursor of [Pd(dicl)2(3pic)2]. Thermal analysis shows that the complex is stable up to 200 o C.

Chemoselective Aerobic Diol Oxidation by Palladium(II)–Pyridine Catalysis

et al. 2011

Neutral and cationic palladium complexes that bear pyridine ligands [i.e., pyridine (Py), 4‐ethylpyridine (4‐EtPy) and 2,4,6‐trimethylpyridine (2,4,6‐Me3Py)] have been isolated and characterized in solution by 1H and 13C{1H} NMR spectroscopy, cyclic voltammetry (CV) and in the solid state by elemental analysis and single‐crystal structure analysis. All palladium compounds have been scrutinized as a precursor to catalyze the aerobic oxidation of diols either in the presence or in the absence of an external base (i.e., K2CO3). As a result, the chemoselective production of the corresponding hydroxy ketones has been achieved. The bis‐cationic palladium complex of the formula [Pd(4‐EtPy)4](OTs)2 (OTs = p‐toluenesulfonate) [5b(OTs)2] emerged as the most promising precursor; it outperformed the neutral precursor that consisted of trans‐[Pd(OAc)2(4‐EtPy)2] (OAc = acetate) and 4‐EtPy [3b/2(4‐EtPy)] (2 mol‐equiv.). An operando high‐pressure (HPNMR) spectroscopic study with the precursor 5b(OTs)2 combined with the results obtained from catalytic reactions has provided insight into the catalytic mechanism that is operative in 5b(OTs)2‐catalyzed aerobic diol oxidation reactions.
