Zhou, Hui;Bae, Han Yong;Leutzsch, Markus;Kennemur, Jennifer L.;Becart, Diane;List, Benjamin research published 《 The Silicon-Hydrogen Exchange Reaction: A Catalytic σ-Bond Metathesis Approach to the Enantioselective Synthesis of Enol Silanes》, the research content is summarized as follows. The use of chiral enol silanes in fundamental transformations such as Mukaiyama aldol-, Michael-, and Mannich reactions, as well as Saegusa-Ito dehydrogenations, has enabled the chem. synthesis of enantiopure natural products and valuable pharmaceuticals. However, accessing these intermediates in high enantiopurity has generally required the use of either stoichiometric chiral precursors or stoichiometric chiral reagents. The authors now describe a catalytic approach in which strongly acidic and confined imidodiphosphorimidates (IDPi) catalyze highly enantioselective interconversions of ketones and enol silanes. These Si-H exchange reactions enable access to enantiopure enol silanes via tautomerizing σ-bond metatheses, either in a deprotosilylative desymmetrization of ketones with allyl silanes as the Si source, or in a protodesilylative kinetic resolution of racemic enol silanes with a carboxylic acid as the silyl acceptor.

Wu, Xiaolin;Wu, Guanglong;Xie, Jiahong;Wang, Qingjie;Liu, Guorui;Liu, Wenbin;Yang, Lili;Zheng, Minghui research published 《 Thermochemical formation of multiple unintentional persistent organic pollutants on metallurgical fly ash and their correlations》, the research content is summarized as follows. Metallurgical processes are currently the predominant anthropogenic sources of multiple unintentional persistent organic pollutants (POPs), including polycyclic aromatic hydrocarbons (PAHs), chlorinated and brominated PAHs (Cl-PAHs and Br-PAHs), polychlorinated biphenyls (PCBs), polychlorinated naphthalenes (PCNs), and polybrominated di-Ph ether (PBDEs). Understanding the formation of multiple POPs is important for source control. These POPs could be formed through fly ash-mediated heterogeneous reactions. In this study, we comprehensively investigated the thermochem. (150-450 °C) formation of these POPs on fly ash samples collected from a secondary aluminum smelter, secondary lead smelter, and iron ore sintering plant. The maximum concentrations of PCNs and PCBs were 154.5 and 181.3 times those in the original fly ash, resp. Formation variations of PAHs, Cl-PAHs and Br-PAHs, and PBDEs were different from that of PCBs and PCNs. The PAHs concentration, which was the highest among the POPs in the original fly ash, decreased sharply by 95% at 150 °C. The ∑₁₉Cl-PAHs and ∑₁₉Br-PAHs increased marginally at 250 °C before decreasing slightly at 350 °C. The PBDE concentrations decreased under 250 °C and increased at 350 °C. PCNs, PCBs, and PCDD/Fs showed good correlations, all of which had a neg. relationship with the PAHs. There were no significant correlations between PAHs and Cl/Br-PAHs.

A practical and efficient synthesis of 4-(triphenylen-2-yl)dibenzothiophene, a phosphorescent host, has been established via ligand-free palladium on carbon (Pd/C) catalyst mediated Suzuki coupling reaction. The process allowed us to recover and reuse the heterogeneous Pd/C catalyst for cost-effectiveness with a conversion yield greater than 90%. Moreover, interesting results on solid-state studies of the sublimed title material have been captured along with its photo-phys. and electrochem. properties, which are appropriate for its use as a host material. Finally, we have fabricated solution-processed organic light-emitting diodes (OLEDs) by using the title material as a host and bis(4-phenylthieno[3,2-c]pyridinato-N,C2 ‘) (acetylacetonate) iridium(III) (PO-01), as a phosphorescent dopant. The devices exhibited efficiencies of ∼9 cd/A at 1000 cd/m², and the results were comparable with the traditional host, 4,4 ‘-bis(N-carbazolyl)-1,1 ‘-biphenyl (CBP).
