Nickel Nanoparticle-catalyzed Carboxylation of Unsaturated Hydrocarbon with CO₂ Using Sulfur-modified Au-supported Nickel Material

Carbon(sp2)‐carbon(sp3) Bond‐forming Cross‐coupling Reactions Using Sulfur‐Modified Au‐Supported Nickel Nanoparticle Catalyst

“…Furthermore, SANi shows high catalytic activity in the Kumada and Negishi coupling reactions of carbon(sp 2 )‐carbon(sp 2 ) bond formation without the use of ligands and can be used repeatedly for more than five times (Scheme 2a) [13] . It has also been reported that SANi can be applied to the immobilization reaction of carbon dioxide on alkenes and alkynes (Scheme 2b) [15] …”

“…[13] It has also been reported that SANi can be applied to the immobilization reaction of carbon dioxide on alkenes and alkynes (Scheme 2b). [15] As mentioned above, carbon(sp 2 )-carbon(sp 2 ) bond-forming cross-coupling reactions using SAPd and SANi have been achieved, but their application to carbon(sp 2 )-carbon(sp 3 ) bondforming cross-coupling reactions has been unexplored, except for the example shown in Scheme 2c. Scheme 2c shows an example of Negishi coupling of 3-iodoanisole and n-butylzinc chloride using SANi, but the yield was low (only 32%).…”

Recent Progress of Metal Nanoparticle Catalysts for C–C Bond Forming Reactions

“…One of the most fundamental supports for metal NPs is inorganic materials such as metal oxides, clay, and so on [31][32][33]. There have been developed many highly active inorganic materials and supported metal NP catalysts, such as those which proceed the C-C bond forming reaction at room temperature [34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51]. Typical recent examples include the following:…”

Ligand-free reductive coupling of aldehydes with 1,3-dienes using a sulfur-modified Au-supported nickel nanoparticle catalyst

“…It has also been reported that SANi can be applied to the immobilization reaction of carbon dioxide on and alkynes (Scheme 3d). 19 Here, we report the unprecedented Ni NP-catalysed reductive coupling of aldehydes with 1,3-dienes. We used SANi as Ni NPs.…”
