Monodisperse amorphous CuB₂₃ alloy short nanotubes: novel efficient catalysts for Heck coupling of inactivated alkyl halides and alkenes

Abstract

CuB23 short nanotubes are efficient catalysts to replace Pd and Ni for Heck-type coupling of inactivated alkyl halides and alkenes.

Retracted Article: Synthesis of octahedral, truncated octahedral, and cubic Rh2Ni nanocrystals and their structure–activity relationship for the decomposition of hydrazine in aqueous solution to hydrogen

“…Excitingly, the Brij-93-capped Rh 2 Ni nanooctahedra exhibited a similar activity to that of the "cleaned" Rh 2 Ni nanooctahedron/C catalyst for lactic acid (LA) hydrogenation, 102 while the PVP-capped nanooctahedra showed a similar activity to that of the surface "clean" Rh 2 Ni nanooctahedron/C catalyst for the Heck reaction. 102,103 Owing to the excellent compatibility of the Rh 2 Ni nanooctahedra with the assistance of capping agents without any loss in activity, which exempted the catalyst from complex post synthesis treatment, our Rh 2 Ni nanooctahedra could find important applications in a vast array of important catalytic reactions.…”

Copper‐Catalyzed Sonogashira‐Cross‐Coupling of Phenols Using Dichloroimidazolidinedione

“…[1][2] So, development of efficient methodologies for generating carbon-carbon bonds established substantial attention. [3][4][5] The Sonogashira CÀ C coupling reaction between aryl halides and alkynes is prosperous as a popular methodology for the construction of C(sp 2 )-C(sp) bonds. Aryl halides are popular coupling partners because of their high reactivity.…”

Asymmetric Intermolecular Heck Reaction of Aryl Halides by Pd-histidine Organocatalysts

“…[19][20][21][22] Unfortunately, the most of these conventional methods were limited to using phosphine ligands. [23][24][25][26][27][28][29][30][31][32][33] As we know, a few reports are available in P-free conditions for this type of reactions that suffer from low selectivity.…”
