In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. In homogeneous catalysis, catalysts are in the same phase as the reactants. 5428-54-6, Name is 2-Methyl-5-nitrophenol, molecular formurla is C7H7NO3. In a document, author is Clegg, Jack K., introducing its new discovery. Product Details of 5428-54-6.
The sequential interaction of preformed [Cu-2(L-1)(2)(THF)(2)] (where H2L1 is 1,1-(1,3-phenylene)-bis(4,4-dimethylpentane-1,3-dione incorporating a 1,3-phenylene linker between its two beta-diketone domains) and [Cu-2(L-4)(2)]center dot 2H(2)O (where H2L4 is 1,1-(4,4′-oxybiphenylene)-bis(4,4-dimethylpentane-1,3-dione) incorporating a flexible oxybiphenylene linkage between the two beta-diketone groups) with the potentially difunctional aliphatic non-planar co-ligands, N-methylpiperazine (mpip), N,N’-dimethylpiperazine (dmpip) and 1,4-thiomorpholine (thiomorph) is reported. A series of extended molecular assemblies exhibiting a range of di- and tetranuclear assemblies were obtained and their X-ray structures determined. Dinuclear [Cu-2(L-1)(2)(mpip)(2)]center dot 2mpip incorporates two 5-coordinate, square pyramidal metal centres as does tetranuclear [{Cu-2(L-1)(2)}(2)(dmpip)(2)]center dot 2dmpip. In contrast, dinuclear [Cu-2(L-1)(2)(dmpip)(4)]center dot dmpip and [{Cu-2(L-1)(2)}(2)(thiomorph)(4)]center dot 3thiomorph each contain two 5-coordinate and two 6-coordinate centres. Each of [Cu-2(L-4)(2)(THF)(2)]center dot 2THF and Cu-2(L-4)(2)(mpip)(2)]center dot H2O incorporate only 5-coordinate metal centres, with the latter complex forming a one-dimensional hydrogen bonded ribbon-like structure directed along the crystallographic a-axis. In keeping with the documented tendency for the smallest, least strained assembly to form in supramolecular self-assembly processes, the incorporation of the flexible oxy linkage between the 4,4′-linked phenylene rings of H2L3 results in generation of a dinuclear [Cu2L2] species rather than a trinuclear (triangular) [Cu3L3] species of the type formed by the more rigid bis-beta-diketonato ligand analogue in which the biphenylene rings separating the beta-diketone domains are directly coupled in their 4,4′ positions.
Product Details of 5428-54-6, The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 5428-54-6 is helpful to your research.
