Magnetically Recoverable Gold Nanorods as a Novel Catalyst for the Facile Reduction of Nitroarenes Under Aqueous Conditions

Threonine stabilizer‐controlled well‐dispersed small palladium nanoparticles on modified magnetic nanocatalyst for Heck cross‐coupling process in water

“…In the following step, several common bases were examined in the model reaction. The results revealed that the presence of base has a crucial effect in the Heck cross-coupling reaction progress ( Table 1, entries [8][9][10][11][12]. Et 3 N afforded higher yield and shorter reaction time than the other bases (Table 1, entry 12).…”

“…Among them, Heck–Mizoroki cross‐coupling is one of the most beneficial reactions for carbon–carbon bond formation due to its high efficiency and atom economy . During the last few decades, various homogeneous, heterogeneous and organometallic systems with special ligands have been developed for the Heck cross‐coupling reaction . Most of them suffer from drawbacks such as tedious multistep synthesis and work‐up, air‐ and moisture‐sensitive ligands, expensive, unstable and toxic ligands such as phosphine, and use of various additives and harmful solvents .…”

“…[7] During the last few decades, various homogeneous, heterogeneous and organometallic systems with special ligands have been developed for the Heck cross-coupling reaction. [8][9][10] Most of them suffer from drawbacks such as tedious multistep synthesis and work-up, air-and moisture-sensitive ligands, expensive, unstable and toxic ligands such as phosphine, and use of various additives and harmful solvents. [11,12] Also, a diverse array of organic and inorganic supports, such as polymers, carbon, clay, ordered silicates and zeolites, have been used as hosts for palladium nanoparticles in cross-coupling reactions.…”

Uniform silver nanoparticles on tunable porous N‐doped carbon nanospheres for aerobic oxidative synthesis of aryl nitriles from benzylic alcohols

“…[32] Recently, we have used carbon as a support for generation of Cu and Au nanoparticles for organic functional group transformations, efficiently. [33][34][35] In the last years, carbon with attractive properties such as porous structure, excellent electrical conductivity, and high stability find widespread applications as support in catalysts. [36] The simplicity of synthesis of carbon nanospheres from inexpensive and available carbon sources (glucose or sucrose) is the one of the main advantages of this catalytic system.…”

Structure‐activity relationship of supported Au catalysts with high catalytic activity by modifying the inactive supports

“…17 In addition, in the past few years, the application of Au nanoparticle on biological chemistry has been uninterruptedly developed and improved. [18][19][20] Although the applications of the Au nanoparticle catalysts are constantly expanding, [21][22][23][24][25] the CO oxidation as a probe reaction has been widely employed to study the mechanism about catalytic reaction of Au nanoparticles. 26 It is noteworthy that these supports of catalysts are almost active.…”
