Palladium particles from oxime-derived palladacycle supported on Fe3O4/oleic acid as a catalyst for the copper-free Sonogashira cross-coupling reaction

Advances in Magnetic Nanoparticles-Supported Palladium Complexes for Coupling Reactions

“…Karami and co-workers describe a recyclable oxime-derived palladacycle immobilized on a highly active Fe 3 O 4 /oleic acid solid support for the copper-free Sonogashira cross-coupling reaction [ 42 ]. The procedure for the preparation of catalyst is shown in Scheme 41 .…”

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

“…Until now, different palladacycles have been immobilized on inorganic and organic supports through covalent or non-covalent interactions [11,12]. Among them, silica-based supports [14][15][16][17][18][19][20][21][22][23][24], organic polymers [19,[25][26][27][28][29][30][31][32][33][34][35][36][37], monolithic supports [38], magnetic nanoparticles [39,40], macrocyclic molecules [41], and Montmorillonite [42,43], are the studied systems. Although these catalysts can be generally reused, a progressive deactivation caused by complex degradation is usually observed, with the reaction products generally being vulnerable to palladium contamination [44].…”

Nano tetraimine Pd(0) complex as an efficient catalyst for phosphine‐free Suzuki reaction in water and copper‐free Sonogashira reaction under aerobic conditions

“…Recently various heterogeneous catalysts have been reported, such as polymer‐supported N ‐heterocyclic carbene–palladium catalyst for Sonogashira reactions, poly(vinyl chloride)‐supported Pd(II) complex for Sonogashira reactions, Pd(II) Schiff base complex supported on multiwalled carbon nanotubes for Suzuki and Sonogashira reactions, palladium supported on feather keratin for Suzuki reactions, palladium particles from oxime‐derived palladacycle supported on Fe 3 O 4 /oleic acid for Sonogashira reactions, PCP‐pincer palladium nanoparticles supported on modified Merrifield resin for carbon–carbon cross‐coupling reactions and HypoGel‐supported palladium nanocatalysts for Suzuki reactions . The features of these catalysts have made them important from environmental and economic points of view due to their facile recycling and ease of separation.…”
