  Substituent effects upon the peak potentials and reductive cleavage rate constants of hydroxy- and methoxy-substituted 9,10-anthraquinones in 50% aqueous CH3CN: do they correlate?

  摘要：

  A variety of hydroxy- and methoxy-substituted 2-(acetoxymethyl)-9,10-anthraquinones (2a-7a) were reduced electrochemically and with dithionite (S2O-4(2-)) in 50% aqueous CH3CN buffers over a wide pH range. Good to excellent yields of their corresponding reductive cleavage products, the substituted 2-methyl-9,10-anthraquinones 2b-7b, were obtained from most of these anthraquinone acetates, but only at higher pH. Rate constants for the reaction of 2-(acetoxymethyl)-9,10-anthraquinone (1a) with excess dithionite ranged from 1.0 x 10(-4) S-1 at pH values less than 7 to 4.0 x 10(-4) S-1 at a pH of 10, demonstrating that loss of acetate occurs in the rate-determining step and that cleavage occurs slower via the anthrahydroquinone of 1a than the conjugate base of the anthrahydroquinone. Substituent effects upon the reductive cleavage process were determined by measuring rate constants for those acetates that react cleanly with dithionite at pH 8. These effects, which are rationalized on the basis of resonance theory and intramolecular H bonding, correlate fairly well with the peak potentials (E(p)) of the reductive cleavage products of these acetates. Thus, electron-donating substituents on an anthraquinone acetate not only make it more difficult to reduce resulting in a more negative E(p) but also enhance the rate of acetate cleavage in the corresponding anthrahydroquinone.

  Magnetic CuFe2O4/g‐C3N4 hybrids were synthesized through a facile method and their catalytic performances were evaluated in click chemistry for the first time. The structural and morphological characterization of prepared materials was carried out by different techniques such as X‐ray diffraction, high‐resolution transmission electron microscopy, field emission scanning electron microscopy, Fourier
