Ebook "Olefin upgrading catalysis by nitrogen-based metal complexes I: State-of-the-art and perspectives" highlights key advances that have occurred in the field of olefin conversion in recent years. The role of homogenous transition metal catalysts which contain an imine functionality is emphasized; their potential applications in the processing and upgrade of olefins to a wide variety of commodity products of very high industrial value is also explored.

The reasonable shifts in FT-IR and NMR spectral signals of the complexes with respect to the free ligand confirm good coordination of the Schiff-base ligand with the metal through imine nitrogen and oxygen atoms of Schiff base moiety. The Schiff-base ligand and the complexes were screened for antimicrobial activity and fluorescent behaviour. From the analytical and spectral data, the stoichiometry was found to be 1:2 for all the complexes. An octahedral structure was proposed. All the complexes were found to be active against bacteria and fungi.

A series of pyrene-based salicylaldimine-type ligands containing n-octyl or cyclohexyl or phenyl groups at imine nitrogen group, 1-hydroxy-2-[(N-substituted-imino)methyl]-pyrenes (octyl 1, cyclohexyl 1b and phenyl 1c), were synthesized and characterized.

Ba hỗn hợp phức Cu(II), Zn(II) và Ni(II) chứa 4 dimethylaminobenzaldehyde-N(4)- morpholinylthiosemicarbazone (L), [Cu(L’)2(H2O)2], [Zn(L)2(H2O)2] và [Ni(L)2(H2O)2] được tổng hợp và xác định cấu trúc dựa trên phân tích dữ liệu từ phổ FT-IR, UV-Vis, NMR 1D-2D và MS. Trong khi phối tử L giữ nguyên cấu trúc trong các phức của Zn(II) và Ni(II) thì trong phức của Cu(II), L đã chuyển hóa thành loại phối tử mới (L’) trong không khí khi có mặt xúc tác Cu2+/EtOH.L phối trí với ion kim loại thông qua nguyên tử nitrogen của nhóm imine và nguyên tử sulfur của nhóm thioketone.

The analysis of IR, UV-vis, MS, 1H-NMR, 13C-NMR, COSY, and HSQC illustrated that HL1, HL2, HL3 were bidentate ligands and bound to the metal through the imine nitrogen and the net negatively charged sulfur in thiol form. Furthermore, it was demonstrated that the chelating ligands in the Pt(II) complexes were in the trans configuration.
