Abstract
In the solvothermal condition, a Pd(II) complex with a in situ synthesis ligand, [Pd(2,2’-bipy)2(CN)2] (1) was obtained and characterized by elemental analysis, IR, UV, TG, and powder X-ray analysis. The single crystal X-ray analysis showed that the title complex is different from the reported 2,2’-bipyridyl-dicyanopalladium(II) (2) in crystal system and structural parameters. The catalytic investigation for the reactions of the disproportionation of hydrogen peroxide and oxidation of sulfide showed that the complex 1 is an active homogeneous catalyst in the presence of imidazole and 2-sulfobenzoic acid, respectively.

In situ ligand synthesis under hydro/solvothermal conditions has already yielded a large number of novel coordination complexes [1]
Acetonitrile is a common organic solvent in the synthesis of coordination complexes, while this solvent can result in the C-C bond cleavage under hydro/solvothermal conditions through the catalysis of metal ions, such as Cu, Mn, Pb, Ir, Ru, and Cd [3]
Summary
In situ ligand synthesis under hydro/solvothermal conditions has already yielded a large number of novel coordination complexes [1]. The solvents used in the solvothermal reaction may make some changes to produce new species [2]. Acetonitrile is a common organic solvent in the synthesis of coordination complexes, while this solvent can result in the C-C bond cleavage under hydro/solvothermal conditions through the catalysis of metal ions, such as Cu, Mn, Pb, Ir, Ru, and Cd [3]. We report the first C-C bond cleavage of acetonitrile in the presence of Pd(II) under solvothermal condition
