Synthesis, characterization, crystal structure and electrochemical behavior of a nickel(II) complex of 5,6-dihydro-2H-pyran-3-aldehyde thiosemicarbazone was written by Harek, Yahia;Larabi, Lahcene;Boukli, Leila;Kadri, Fatima;Benali-Cherif, Noureddine;Mostafa, Mohsen M.. And the article was included in Transition Metal Chemistry (Dordrecht, Netherlands) in 2005.Synthetic Route of C6H8O2 This article mentions the following:
A new NiII complex of 5,6-dihydro-2H-pyran-3-aldehyde thiosemicarbazone (HDPTSC) was synthesized and characterized by microanalyses, magnetic susceptibility, molar conductance measurements and by spectral methods (IR, UV-visible, 1H-NMR). The structure of [Ni(DPTSC)2]· DMF was solved using x-ray diffraction and is highly sym. with a trans arrangement of the two bidentate ligands. The thiosemicarbazone coordinates as an anionic ligand via the thiosemicarbazone moiety’s azomethine N and thiolate S [on loss of the N2 H]. The electrochem. behavior of the ligand and its NiII complex, determined by cyclic voltammetry, shows that the redox process of the ligand was highly irreversible, whereas the redox process of the NiII complex was observed as a one electron transfer process in a quasi-reversible and diffusion-controlled reaction. In the experiment, the researchers used many compounds, for example, 5,6-Dihydro-2H-pyran-3-carbaldehyde (cas: 13417-49-7Synthetic Route of C6H8O2).
5,6-Dihydro-2H-pyran-3-carbaldehyde (cas: 13417-49-7) belongs to tetrahydropyran derivatives. Tetrahydropyrans are also used as important solvents, as chemical intermediate and as monomer for ring-opening polymerization. One classic procedure for the organic synthesis of tetrahydropyran is by hydrogenation of the 3,4-isomer of dihydropyran with Raney nickel.Synthetic Route of C6H8O2
