In this work, the catalytic efficiency of a novel biorelevant triazine (TA)-based pantothenate (vitamin B5) copper(II) complex [Cu(II)-TA/B5] in the aerobic oxidation of benzyl alcohols and tandem synthesis of bis(indolyl)methanes was exploited. The star-shaped catalyst was characterized by different techniques such as FT-IR, EDX, ICP, TEM, and TGA. TEM images revealed a honeycomb structure resulting from the accumulation of nanoparticles with size ranging between 2–6 nm. The high yields and excellent selectivity were obtained for the production of various benzaldehydes and bis(indolyl)methanes under aerobic conditions. Recycling tests, spectroscopic data, and leaching experiments testified that the title heterogeneous biorelevant catalyst preserved its activity and structural integrity during oxidation and coupling reactions. The presented catalytic systems qualify all requirements for efficient catalytic systems for applied goals. [ABSTRACT FROM AUTHOR] |
