Cu(OAc)2 entrapped on ethylene glycol-modified melamine–formaldehyde polymer as an efficient heterogeneous catalyst for Suzuki–Miyaura coupling reactions

A novel COF-based Cu heterogeneous catalyst for a green Suzuki cross-coupling reaction under mild conditions

“…This corresponds to the Cu(OAc) 2 being incorporated on the COF precursors, which is consistency with previous reported literature. 18 The surface area and porosity of the copper-based catalysts and precursors were determined by nitrogen adsorption-desorption analysis. The nitrogen adsorption-desorption experiment of the two copper-based catalysts at 77 K (Fig.…”

“…A typical strategy in developing heterogeneous copper-based catalysts is to deposit the copper species onto various solid supports. Different substrates such as porous materials, 7 metal–organic-frameworks, 8 and cross-linked polymers 9 have been used to carry copper ions as solid catalysts for the mediation of various cross-coupling reactions. Siva et al 9 successfully synthesized the heterogeneous catalyst Cu@MCOP by immobilization of copper onto a glycol-modified melamine-formaldehyde-based polymeric material.…”

Siva et al 9 successfully synthesized the heterogeneous catalyst Cu@MCOP by immobilization of copper onto a glycol-modified melamine-formaldehyde-based polymeric material. Cu@MCOP showed effective catalytic performance for the reaction of aryl iodide with a variety of arylboronic acids in DMF at 70 °C.…”

Pd based on 2‐Aminopyrimidine and 1H‐benzo[d]imidazol‐2‐amine functionalizedFe3O4 nanoparticles as novel recyclable magnetic nanocatalysts for Ullmann coupling reaction

“…[1,2] In other words, this reaction has attracted recently high interest from the industry and used by chemists to produce a C-C bond between two aromatic nuclei in the presence of copper powder as a Cheap and economical catalyst to prepare the corresponding symmetrical biaryl. [3,4] and nowadays N-, O-, S-, P-and C-aryl bonds formation are easily accessible through these processes in many bioactive organic compounds. [5] For first time, aryl iodides were used in coupling reactions that were broaded by copper at high temperature conditions.…”

Preparation and characterization of Cu supported on 2‐(1H‐benzo[d]imidazol‐2‐yl)aniline‐functionalized Fe3O4 nanoparticles as a novel magnetic catalyst for Ullmann and Suzuki cross‐coupling reactions

“…[10,11] Also, to form C& C bonds in biaryl or diphenyl compounds, the most significant procedure is through transition metal-catalyzed Suzuki cross-coupling reactions between an aryl electrophile and aryl nucleophile or aryl halides and phenylboronic acid. [12] Diaryls are a valuable class of organic compounds with wide applicability in the polymer and life science industries as well the chemical industry. [13,14] A number of them display substantial special biological and pharmacological activities.…”
