Reference of 72287-26-4, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 72287-26-4, [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II), introducing its new discovery.

Functional nanosized cage complexes with an octahedral framework have been synthesized by the facile self-assembly reactions of six 90 Pd II-containing compounds {[Pd(dppf)(OTf)2] or [Pd(PPh 3)(OTf)2], dppf = 1,1?-bis(diphenylphosphanyl) ferrocene, OTf = trifluoromethylsulfonate} and four 120 functional tritopic ligands [2,4,6-tri(4-pyridyl)-1,3,5-triazine] in acetone. Diffusion-ordered NMR spectroscopy (DOSY) and AFM images clarify the formation of 3-4 nm nanoparticles. These highly symmetrical cage complexes are discrete, face-directed, functional nanoparticles with symmetrical octahedral structures. The self-assembled functional cage complexes exhibit interesting electrochemical activities, and thus will potentially be useful in the catalysis of redox reactions, the encapsulation of sizeable guest molecules and the control of organic synthetic reactions. The appropriate stoichiometric combination of 90 PdII-containing units with 120 tritopic units affords octahedral symmetrical nanocages through covalently linked functional groups, which exhibit interesting electrochemical activities.

Herein, we demonstrate the first example of a multistep solid-state organic synthesis, in which a new imine-linked two-dimensional covalent organic framework (COF-170, 1) was transformed through three consecutive postsynthetic modifications into porous, crystalline cyclic carbamate and thiocarbamate-linked frameworks. These linkages are previously unreported and inaccessible through de novo synthesis. While not altering the overall connectivity of the framework, these chemical transformations induce significant conformational and structural changes at each step, highlighting the key importance of noncovalent interactions and conformational flexibility to COF crystallinity and porosity. These transformations were assessed using 15N multiCP-MAS NMR spectroscopy, providing the first quantitation of yields in COF postsynthetic modification reactions, as well as of amine defect sites in imine-linked COFs. This multistep COF linkage postsynthetic modification represents a significant step toward bringing the precision of organic solution-phase synthesis to extended solid-state compounds.

Provided are asymmetric arylamine derivatives for an organic electroluminescent element, represented by the formula (1), which is prepared by sequentially inducing a secondary amine and a tertiary amine to an aryl compound Ar core so that they do not include a symmetrical axis and a symmetrical surface in a molecule, a manufacturing method of the same, an organic thin layer material including the asymmetric arylamine derivatives, and an organic electroluminescent element employing the same: wherein Ar represents a C10-C20 divalent aryl group, Ar1 is a divalent C6-C30 aryl group, and Ar2 to Ar5 each independently represents a divalent C6-C30 aryl group, at least one of Ar2 to Ar5 having a different structure when the secondary amine and the tertiary amine in Ar are substituted at symmetrical positions, and Ar2 to Ar5 having the same structure or different structures when the secondary amine and the tertiary amine in Ar are substituted at asymmetrical positions. The asymmetric arylamine derivative can be used in forming an organic thin layer for an organic electroluminescent element. When the organic electroluminescent element is formed using a dopant as an emitting material, the asymmetric arylamine derivative exhibits superb emission efficiency and an excellent lifetime characteristic in a blue wavelength region.

Under microwave assistance, 2,6-bis(benzimidazolyl)-pyridine has been concisely synthesized and further productively converted to the functional molecule BMBP via accessible N-alkylation reaction. For the introduction of alkoxyalkyl chain, this original substance BMBP with better solubility in water exhibits specific fluorescence response toward Zn2+ from colourless to blue in aqueous solution. A sequential detection for picric acid (PA) can be conducted in this following system, showing the high selectivity and sensitivity of quenching over other analogues. On the basis of the comparison with the control BMBB, a cascade sensing mechanism has been disclosed to accelerate the recognition of structure-property relationship, which is fully supported by LC-MS, 1H NMR, lifetime measurement and theoretical calculation. Noteworthily, BMBP is also readily available for practical application not only in quantitative determination of Zn2+ and PA in real water samples, but also in visible detection of two analytes in multiple forms on paper test strips, offering convenient process for low-cost, portable and versatile sensing device.

The kinetics of the oxidative addition of bidentate ligand-chelated Pd 0 complexes to phenyl iodide and bromide has been studied via cyclic voltammetry. The dibenzylideneacetone (dba) delivered by the palladium precursor Pd(dba)2 was found to affect the concentration of the more reactive dba-free Pd0 complex and consequently the kinetics of the overall oxidative addition. The complexes generated from Pd(dba)2 and PhSCH2CH2SPh (pte) were found to be considerably more reactive than those generated from Pd(dba)2 and Ph 2PCH2CH2-PPh2 (dppe). The former complexes can react with PhBr at low temperatures.
