Kubota, Koji;Takahashi, Rina;Ito, Hajime research published 《 Mechanochemistry allows carrying out sensitive organometallic reactions in air: glove-box-and-Schlenk-line-free synthesis of oxidative addition complexes from aryl halides and palladium(0)》, the research content is summarized as follows. Organic reactions that employ moisture- and/or oxygen-sensitive reagents or intermediates usually involve the use of glove-box or Schlenk-line techniques as well as dry and degassed solvents. Unfortunately, these requirements may greatly reduce the utility of the targeted organic mols. Herein, we demonstrate that solvent-free mechanochem. synthetic techniques allow using highly oxygen-sensitive palladium(0) species in air for the stoichiometric oxidative addition of aryl halides. The low diffusion efficiency of gaseous oxygen in crystalline or amorphous solid-state reaction mixtures should be the main reason for the low impact of the presence of atm. oxygen on the sensitive oxidative addition reactions under the applied conditions. This study thus illustrates the outstanding potential of mechanochem. to serve as an operationally simple, glove-box-and-Schlenk-line-free synthetic route to organometallic compounds and other valuable synthetic targets, even when sensitive reagents or intermediates are involved.

Kubota, Koji;Takahashi, Rikuro;Uesugi, Minami;Ito, Hajime research published 《 A Glove-Box- and Schlenk-Line-Free Protocol for Solid-State C-N Cross-Coupling Reactions Using Mechanochemistry》, the research content is summarized as follows. Carbon-nitrogen (C-N) bond-forming cross-coupling reactions catalyzed by palladium-based catalysts, the so-called Buchwald-Hartwig aminations, have been widely employed for the synthesis of pharmaceuticals and aryl-amine-based organic materials in academic and industrial settings. However, in solution, these reactions usually require glove-box and Schlenk line techniques, which greatly reduces their practical utility. Here, we report the development of operationally simple mechanochem. C-N cross-coupling reactions in the solid-state. Intensive investigations of various ball milling parameters revealed that the air-stable ligand tri(1-adamantyl)phosphine can be used to achieve solid-state coupling reactions between aryl halides and diarylamines with high efficiency. Notably, all exptl. operations of the developed protocol can be carried out in air, thus providing a more convenient, industrially attractive, and sustainable alternative to conventional solution-based palladium-catalyzed C-N coupling reactions. The development of operationally simple mechanochem. solid-state C-N cross-coupling reactions in air is reported.

Jin, Rong;Liu, Guorui;Jiang, Xiaoxu;Liang, Yong;Fiedler, Heidelore;Yang, Lili;Zhu, Qingqing;Xu, Yang;Gao, Lirong;Su, Guijin;Xiao, Ke;Zheng, Minghui research published �Profiles, sources and potential exposures of parent, chlorinated and brominated polycyclic aromatic hydrocarbons in haze associated atmosphere� the research content is summarized as follows. Profiles, sources, and potential exposures of chlorinated and brominated polycyclic aromatic hydrocarbons (ClPAH, BrPAH) in haze associated atm. remain unclear. Haze events occur frequently during the heating period in Beijing, China, and provide a typical urban context to assess concentrations, profiles, sources, and potential exposure to ClPAH, BrPAH, and their non-halogenated parent compounds (PAH) in air. Average PAH, ClPAH, and BrPAH concentrations during heating periods (with more frequent haze events) were �-9 times higher than during non-heating periods. Particulate matter (PM)-associated ClPAH and BrPAH concentrations were higher in heating vs. non-heating periods; for gas-associated ClPAH and BrPAH, this distinction was not significant. Congener patterns and profiles indicated that with increasing coal combustion in the heating period, PAH and ClPAH concentrations in air were elevated vs. the non-heating period. Inhalation of PM-associated PAH, ClPAH, and BrPAH accounted for higher exposure than inhalation of gas phase and dermal contact of gaseous and particulate phases. Results determined the particulate phase is the dominant exposure pathway for atm. PAH, ClPAH, and BrPAH during haze events, which is different from previous studies.

Jin, Rong;Liu, Guorui;Zheng, Minghui;Jiang, Xiaoxu;Zhao, Yuyang;Yang, Lili;Wu, Xiaolin;Xu, Yang research published ã€?Secondary Copper Smelters as Sources of Chlorinated and Brominated Polycyclic Aromatic Hydrocarbonsã€? the research content is summarized as follows. The generation and extent to which chlorinated and brominated polycyclic aromatic hydrocarbons (Cl/Br-PAH) are formed and released from secondary Cu smelters are unknown. This field study is the first to identify secondary Cu smelters as new Cl/Br-PAH sources. Mass concentrations of âˆ?sub>19Cl-PAH and âˆ?sub>19Br-PAH were 5.8-271 ng/Nm³ and 0.59-52.4 ng/Nm³, resp. A comparison of Cl/Br-PAH concentrations in secondary Cu smelting flue gas and fly ash indicated that using scrap Cu as raw material or adding coal or heavy oil as reductant may contribute to increased formation and elevated emission of Cl/Br-PAH. Cl/Br-PAH congener profiles in secondary Cu smelting flue gas and fly ash were different than those from waste incinerators and other previously reported sources; thus, they could be used as possible fingerprints and source apportionments for environmental Cl/Br-PAH. Atm. Cl/Br-PAH concentrations in the workplace or smelter surroundings were determined and potential exposure was assessed. Although chlorination of PAH was previously recognized as an important Cl/Br-PAH formation pathway, this was not verified to be the major Cl/Br-PAH formation pathway for secondary Cu smelters in this work.

Jin, Rong;Yang, Lili;Zheng, Minghui;Xu, Yang;Li, Cui;Liu, Guorui research published ã€?Source identification and quantification of chlorinated and brominated polycyclic aromatic hydrocarbons from cement kilns co-processing solid wastesã€? the research content is summarized as follows. Chlorinated and brominated polycyclic aromatic hydrocarbons (Cl/Br-PAHs) are widespread persistent organic pollutants (POPs) in environments. Identifying the new sources of Cl/Br-PAHs is important for implementing source control and reducing environmental risk. Although co-processing of solid wastes by cement kilns increased recently, the occurrences and characteristics of Cl/Br-PAHs as emerging POPs during cement kiln co-processing solid wastes have not been investigated. This study firstly investigated the occurrences, characteristics, and variations of Cl/Br-PAHs from four cement kilns co-processing different solid wastes. The concentration ranges of Cl-PAHs and Br-PAHs in stack gas samples from the investigated cement kilns were 15.6-94.1 ng m^-3 and 1.04-4.28 ng m^-3, resp. Emission factors of Cl-PAHs and Br-PAHs through stack gases were 29.9-275μg t^-1 and 3.0-8.3μg t^-1, resp. Variations of Cl/Br-PAHs in particle samples collected from different process stages within the cement kiln system indicated that the kiln end was the major formation zone for Cl/Br-PAHs. Congener profiles of Cl/Br-PAHs varied with the co-processed solid waste types, indicating the important influence of raw material compositions Calculations of net emissions of Cl/Br-PAHs within the cement kiln systems suggested efficient destruction (87.6%-98.8%) of Cl/Br-PAHs by the cement kilns.
