Face‐Directed Tetrahedral Organic Cage Anchored Palladium Nanoparticles for Selective Homocoupling Reactions
نویسندگان
چکیده
The Cover Feature shows the formation of two face-directed truncated tetrahedral enantiopure organic cages by employing dynamic imine condensation reactions a hexa-aldehyde precursor with trans-oriented diamines separately. In view its intrinsic porosity combined presence multiple vicinal di-imine corners and stable aromatic backbones, one was used as template for nucleation ultrafine Pd-nanoparticles (PdNPs). cage-PdNPs hybrid further utilized suitable catalyst selective additive-free C−C homocoupling aryl heteroaryl halides under heterogeneous conditions. Moreover, composite material exhibited high durability thermal stability several catalytic cycles without any agglomeration. More information can be found in Research Article P. S. Mukherjee co-workers.

متن کاملPalladium-catalyzed homocoupling reactions between two Csp(3)-Csp(3) centers.
[reaction: see text] A novel palladium-catalyzed coupling reaction between two Csp(3)-Csp(3) centers has been investigated. This protocol is initiated by the oxidative addition of an alpha-halo carbonyl compound to a palladium(0) species, followed by the double transmetalation. The key dialkyl palladium intermediate undergoes reductive elimination to form the desired coupling product.

A novel procedure for the preparation of biaryl compounds by Pd-catalyzed homocoupling of N'-tosyl arylhydrazine has been described. N'-Tosyl arylhydrazine, as a readily available and stable coupling partner, demonstrated its generality in the homocoupling reactions. The scope of the reaction and possible mechanism have also been investigated.
متن کاملTemplate synthesis of gold nanoparticles with an organic molecular cage.
We report a novel strategy for the controlled synthesis of gold nanoparticles (AuNPs) with narrow size distribution (1.9 ± 0.4 nm) through NP nucleation and growth inside the cavity of a well-defined three-dimensional, shape-persistent organic molecular cage. Our results show that both a well-defined cage structure and pendant thioether groups pointing inside the cavity are essential for the Au...
متن کاملPalladium-Catalyzed Cross-Coupling Reactions of Perfluoro Organic Compounds
In this review, we summarize our recent development of palladium(0)-catalyzed cross-coupling reactions of perfluoro organic compounds with organometallic reagents. The oxidative addition of a C–F bond of tetrafluoroethylene (TFE) to palladium(0) was promoted by the addition of lithium iodide, affording a trifluorovinyl palladium(II) iodide. Based on this finding, the first palladium-catalyzed c...
