New research progress on 538-58-9 in 2021. In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. Formula: C17H14O, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 538-58-9
(Chemical Equation Presented) The synthesis of monodisperse oligo(p-phenyleneethynylene)s 8an with alternating 2,5-dihexyl-1,4-phenylene and 6,14-di-tert-butyl-1,4-triptycylene units and orthogonally protected alkyne end groups is reported. Starting from 6,14-di-tert-butyl-1-(2-triisopropylsilylethynyl)-4-(2-trimethylsilylethynyl) -triptycene (5a), 1,4-dihexyl-2,5-diiodobenzene (10), and 1,4-dihexyl-2-iodo-5- (3-hydroxyprop-1-ynyl)-benzene (9), oligomers with up to four repeating units, i.e., eight phenyleneethynylene units, were prepared through a partially divergent-convergent route with the alkynyl-aryl (Sonogashira-Hagihara) coupling as the key reaction. The starting compound 5a was prepared from triptycenequinone through a sequence of addition of 2- trialkylsilylethynyllithium, reduction and concomitant elimination of water, conversion of the phenol into a triflate, and finally Pd/Cu-catalyzed coupling with trialkylsilylethyne. A similar access to the key compound for a stringent divergent-convergent route, 6,14-di-tert-butyl-1-(3-hydroxybut-1-ynyl)-4-(2- triisopropylsilylethynyl)triptycene (6), is reported. The optical properties of the oligomers 8an and the corresponding oligo(2,5-dihexyl-1,4- phenyleneethynylene) s in dilute solution are almost identical, whereas they differ significantly for the solid, undiluted compounds.
I am very proud of our efforts over the past few months and hope to 538-58-9 help many people in the next few years.
