A Ni0 σ-Borane Complex Bearing a Rigid Bidentate Borane/Phosphine Ligand: Boryl Complex Formation by Oxidative Dehydrochloroborylation and Catalytic Activity for Ethylene Polymerization was written by Seidel, Falk William;Nozaki, Kyoko. And the article was included in Angewandte Chemie, International Edition in 2022.Electric Literature of C19H15Cl This article mentions the following:
While of interest, synthetically feasible access to boryl ligands and complexes remains limited, meaning such complexes remain underexploited in catalysis. For bidentate boryl ligands, oxidative addition of boranes to low-valent IrI or Pt0 are the only examples yet reported. As part of authors interest in developing improved group 10 ethylene polymerization catalysts, they present here an optimized synthesis of a novel, rigid borane/phosphine ligand and its Ni0 σ-borane complex. From the latter, an unprecedented oxidative dehydrochloroborylation, to give a NiII boryl complex, was achieved. Furthermore, this new B/P ligand allowed the nickel-catalyzed polymerization of ethylene, which suggests that Ni0 σ-hydroborane complexes act as masked NiII boryl hydride reagents. In the experiment, the researchers used many compounds, for example, (Chloromethanetriyl)tribenzene (cas: 76-83-5Electric Literature of C19H15Cl).
(Chloromethanetriyl)tribenzene (cas: 76-83-5) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Electric Literature of C19H15Cl
