One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, category: pyridazine, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 14161-11-6, Name is 3,4,5-Trichloropyridazine, molecular formula is C4HCl3N2
Template synthesis and X-ray structure of the tris-glyoximate iron(II) clathrochelates with terminal reactive groups
One-pot template condensation of glyoxime with the corresponding functionalized phenylboronic acids on an iron(II) ion as a matrix afforded 3- and 4-substituted phenylboron-capped tris-glyoximate iron(II) clathrochelates with terminal amine, formyl (acetal) and vinyl groups; those with acetal groups were converted into the formyl-terminated cage complexes using H+-catalyzed hydrolysis. The complexes obtained were characterized using elemental analysis, MALDI-TOF mass spectrometry, IR, UV?Vis,1H and13C NMR spectroscopies, and by single crystal X-ray diffraction (for three of these clathrochelates). Their molecules possess a geometry intermediate between a trigonal prism (TP) and a trigonal antiprism (TAP) and the bite angles alpha remain almost constant being in the range 77?79, whereas the heights h of FeN6-coordination polyhedra depend on the distortion angle phi values (from 12.2 to 20.7) thus being in the range 2.36?2.37?A. An encapsulated iron(II) ion is situated almost in the centre of cage frameworks and the average chelate [Formula presented] bonds in these tris-glyoximate frameworks are substantially shorter than those for their aliphatic and aromatic analogs. The crystal packings are governed by weak supramolecular hydrophobic interactions and an absence of the steric hindrances between the ribbed substituents (hydrogen atoms) allowed to form intermolecular pi?pi interactions. As follows from single crystal X-ray diffraction data, the synthesized macrobicyclic tris-glyoximates with reactive terminal groups, which the macrobicyclic molecules contain no bulky ribbed substituents, have large ligand aspect ratio and, therefore, they seem to be promising syntones and building blocks for preparation of covalent (including imine and amine) and coordination metallomacrocycles, MOFs and cages (capsules) with big voids and cavities as hosts, suitable for inclusion of various organic and inorganic guests.
