Recyclable N-heterocyclic carbene/palladium catalyst on graphene oxide for the aqueous-phase Suzuki reaction

Coordination chemistry on carbon surfaces

“…Zhang [409] and Xia and Zheng [410] used EDC/NHS amidation to covalently anchor ruthenium complexes on CNTs for electrochemiluminescence studies (Table 24, entries 1-2). Similarly, EDC/NHS activation system allowed Kim [411] to prepare supported NHC-based catalysts via the covalent attachment of an imidazolium on the carboxylate functionalities of GO (Table 24, entry 3). The DCC/HOBT activation system was recently reported for the preparation of a ferrocene/porphyrin/SWCNT triad hybrid (Table 24, entry 4) [412].…”

Graphene Oxide-Supported Oxime Palladacycles as Efficient Catalysts for the Suzuki–Miyaura Cross-Coupling Reaction of Aryl Bromides at Room Temperature under Aqueous Conditions

“…Oxime palladacycles are considered reservoirs of highly active palladium nanoparticles [65][66][67]. Usually, PdNps supported on graphene materials are prepared by reduction of a Pd salt or Pd catalyst in the presence of the corresponding carbonaceous support [44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61]. Then, we next turned our attention to the reduction of 1 with NaBH4 and the catalytic activity of the supported PdNPs was thus obtained.…”

“…This type of catalyst has been mainly used in the Suzuki-Miyaura cross-coupling reaction [45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62]. However, to the best of our knowledge, only very recently has some attention been paid to the immobilization of palladacycles to graphene materials, with two studies having been reported so far using covalent immobilization strategies [63,64].…”

Surfactant‐Exfoliated Highly Dispersive Pd‐Supported Graphene Oxide Nanocomposite as a Catalyst for Aerobic Aqueous Oxidations of Alcohols

“…[18][19][20] GO has also been synthesized and reported as catalytically active in an umber of chemical reactions. [21][22][23][24][25] Nagarkar and co-workers reported the catalytic activity of Pd-nanoparticle-supported GO (Pd@GO) in SuzukiMiyaura cross-coupling reactions. [24] Various reduced binary noble metals (Pt, Ag, Pd)s upported on GO are also recyclable catalysts developed for similar chemistries including Pd-catalyzed Suzuki reactions.…”

“…[47] Synthesis of Pd@GO was accomplished according to the literature [25] with as light modification. The solution of Na 2 PdCl 4 (0.092 g/4 mL) was added dropwise to the GO mixture.…”
