The article conveys some information:
The unification of CuCl2 ·2H2O and NiCl2·6H2O with the support of graphitic carbon nitride yielded to form an efficient, synergistic, bimetallic nano-catalyst CuO-NiO@g-C3N4. Catalyst with three different molar ratios of Cu and Ni, i.e., Cu75Ni25 (Cu:Ni = 3:1; catalyst-a), Cu50Ni50 (Cu:Ni = 1:1; catalyst-b), and Ni66Cu33 (Ni:Cu = 2:1; catalyst-c), was synthesized, and their catalytic activity was examined The synergistic interaction of one metal with the other on the surface of extremely stable graphitic carbon nitride has enhanced the catalytic performance in the synthesis of triazoles I (R1 = Ph, (4-bromophenyl)methyl, 2-hydroxy-1-phenylethyl, etc.; R2 = H, 4-F, 3-Me, 4-Me, 4-OMe), tetrazoles II (R3 = Ph, pyrazin-2-yl, 4-formylphenyl, etc.), and bis-triazole derivatives III to such a distinguished level (in ppm level), which a monometal fail to possess. The aforementioned statement has been supported by the catalytic activity data provided for both the monometallic and bimetallic catalyst herein. In addition to this, benign reaction conditions, in situ generation of azides, wide reaction scopes, and reusability of the catalyst were also the major advantages leading toward safe and sustainable chem. beyond doubt. In the part of experimental materials, we found many familiar compounds, such as 1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7Product Details of 622-95-7)
1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7) undergoes carbonylation in the presence of dimer of chloro(1,5-cyclooctadiene)rhodium(I) to yield the corresponding phenylacetic acid.Product Details of 622-95-7 It can be synthesized by reacting 4-chlorobenzyl alcohol with bromodimethylsulfonium bromide (BDMS) It can also be synthesized by refluxing a mixture of 4-chlorobenzaldehyde, chlorotrimethylsilane, 1,1,3,3-tetramethyldisiloxane and lithium bromide.
