Octanuclear Palladacycles with B(3)–H Bond Activation of o‐Carborane^†

Abstract

Comprehensive Summary Herein, we describe the synthesis of a carborane‐supported octanuclear palladacycle complex, Pd8(o‐C2B10H10CS2CH3)4Cl4(CH3CN)4 (complex 1), with B(3)–H activations on o‐carborane ligand. The substitution reaction of 1 has been explored, and three of its substituted complexes Pd8(o‐C2B10H10CS2CH3)4Cl4(L)4 (L = tBuNC, 2; L = C5H5N, 3; L = C4H8S, 4) have been synthesized. The m‐ and p‐carborane disubstituted ligands m‐ and p‐C2B10H10(CS2CH3)2 (ligands 5 and 6) as well as their B—H activated carborane complexes [m‐C2B10H9(CS2CH3)2PdCl] (7) and [p‐C2B10H8(CS2CH3)2][PdCl(tBuNC)]2 (8) have also been synthesized by the similar method. All of these complexes have been characterized, including X‐ray single crystal diffraction, NMR spectroscopy, IR spectroscopy and elemental analysis methods.

Rational Fabrication of Fe3O4/Co3O4/Graphdiyne Tandem Heterojunction toward Optimized Photocatalytic Hydrogen Evolution

“…However, excessive loading not only masks the active sites of GDY, which is unable to carry out the redox reaction due to the inability to bind H þ in the water, but also the Pinby effect of the shielding caused by the excessive loading hinders the incidence of light and reduces the utilization of light. [44] In general, only dye molecules adsorbed on the semiconductor surface may effectively engage in light absorption and electron transfer in the dye sensitization system, whereas the remaining dye molecules in the solution barely contribute to the hydrogen evolution reaction. [45] Therefore, it is necessary to study the effect of EY addition on the hydrogen evolution activity of the catalyst during the EY sensitization system.…”

Nickelacarborane-Supported Bis-N-heterocyclic Carbenes

“…Replacing one of the carboranes’ vertexes with metal ions leads to the formation of metallacarboranes, which have been extensively studied since their discovery by Hawthorne in 1965 . They were usually prepared from nido -[C 2 B 9 ] carborane species, as the nido -carborane dianions (dicarbollide, Scheme ) could mimic the behavior of cyclopentadienyl anions (Cp – /Cp* – ), allowing for the formation of metallacarboranes with various metals, including most transition metals and even some main-group metals . Their functionalization can be achieved at carbon atoms with groups such as alkyl, aryl, phosphino, etc.…”

Supramolecular Architectures Bearing Half-Sandwich Iridium- or Rhodium-Based Carboranes: Design, Synthesis, and Applications

“…Carboranes are a class of carbon–boron molecular clusters that exhibit three-dimensional (3D) aromaticity and have been used as functional building blocks in materials science, medicine, , and organometallic − /coordination chemistry . Additionally, the unique spatial configurations and weak interactions are excellent for introducing carborane clusters into supramolecular complexes.…”
