In situ ligands syntheses involving malic acid in hydrothermal condition

Three kinds of in situ ligands syntheses involving malic acid, i.e. hydration, intra-molecular dehydration and isomeric transformation, have been found during studying on the syntheses of compounds 1–5. According these results, it can be concluded that the nature of metal atom affects strongly the in situ ligand synthesis, vice versa; the in situ ligand synthesis is favorable to the formation of coordination compound.

Five compounds have been synthesized by hydrothermal reactions, from which three kinds of in situ ligands syntheses involving malic acid, addition, intra-molecular dehydration and isomeric transformation, have been discovered. According these discoveries, it can be concluded that the nature of metal atom strongly affects the in situ ligand synthesis, vice versa, the in situ ligand synthesis is benefit to the formation of coordination compound.Figure optionsDownload as PowerPoint slide
