In this work, the catalytic efficiency of a novel bio-relevant 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 bio-relevant 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.

The skeletal photorearrangement including 6π-electrocyclization induced by UV light ofortho-halogen-substituted diarylethenes has been studied. It has been found that the reaction pathways leading to bi- or tricyclic frameworks depend on the kind of halog
FeCl3·6H2O as a Mild Catalyst for Nucleophilic Substitution of Symmetrical Bis(indoyl)methanes
Chantana, Chayamon,Jaratjaroonphong, Jaray
, p. 2312 - 2327 (2021/02/09)
In this paper, unsymmetrical bis(indolyl)methane (BIM) and 3-alkylindole derivatives are smoothly synthesized from symmetrical BIMs with a variety of nucleophiles including heteroaromatic/aromatic compounds, allylsilane and alkynylsilane. FeCl3·6H2O is found to be a mild and highly effective catalyst for this nucleophilic substitution reaction in which N-methyl-2-phenylindole behaves as a good leaving group in the Csp3-Csp2 bond cleavage reaction. The operational ease, nonexpensive and environmentally friendly catalyst, mild reaction conditions, broad functional group tolerance, and scalability of this reaction strategy are advantages of the present procedure.
