4Computational studies of σ-type weak interactions between NCO/NCS radicals and XY(X = H,Cl;Y = F,Cl,and Br)显示文摘The triatomic radicals NCO and NCS are of interest in atmospheric chemistry,and both the ends of these radicals can potentially serve as electron donors during the formation of σ-type hydrogen/halogen bonds with electron acceptors XY(X = H,Cl;Y = F,Cl,and Br).The geometries of the weakly bonded systems NCO/NCS···XY were determined at the MP2/aug-cc-pVDZ level of calculation.The results obtained indicate that the geometries in which the hydrogen/halogen atom is bonded at the N atom are more stable than those where it is bonded at the O/S atom,and that it is the molecular electrostatic potential(MEP)-not the electronegativity-that determines the stability of the hydrogen/halogen bond.For the same electron donor(N or O/S) in the triatomic radical and the same X atom in XY,the bond strength decreases in the order Y = F > Cl > Br.In the hydrogen/halogen bond formation process for all of the complexes studied in this work,transfer of spin electron density from the electron donor to the electron acceptor is negligible,but spin density rearranges within the triatomic radicals,being transferred to the terminal atom not interacting with XY.LI XiaoYan ZENG YanLi ZHANG XueYing ZHENG ShiJun MENG LingPeng 2012Science China Chemistry2012,55,7:1

10Halogen Bond Catalysis on Carbonyl-Olefin Ring-Closing Metathesis Reaction:Comparison with Lewis Acid Catalysis显示文摘The carbonyl-olefin ring-closing metathesis reactions have become a powerful tool for carbon-carbon bond formation.In this work,the halogen bond catalysis and classical Lewis acid catalysis on the carbonyl-olefin ring-closing metathesis reaction were investigated by density function theory.For both the halogen bond catalysis and classical Lewis acid catalysis,the carbonyl-olefin ring-closing me-tathesis reaction occurs by[2+2]-cycloaddition process and[2+2]-cycloreversion process,the reaction energy barriers are low,there-fore,it can be performed easily at room temperature.The essential difference of the two kinds of catalysts is that the catalytic mecha-nism of halogen bond catalysis is mainly contribution of electrostatic interaction,while that of classical Lewis acid catalysis is mainly catalyzed by orbital interaction.The halogen bond donor catalysts(ICI_(3),IF_(3))are expected to be efficient catalysts for the reaction and further promote the chemical synthesis of carbonyl-olefin ring-closing metathesis reaction.Ying Li Yuanyuan Sun Lingpeng Meng Qingzhong Li Yanli Zeng 2022Chinese Journal of Chemistry2022,40,11:0

14Preliminary PET/CT Study of ^(18)F-FDG Uptake in Cervical and Supraclavicular Brown Adipose Tissue显示文摘OBJECTIVE The clinical use of PET/CT in oncology has led to the realization that 18F-FDG uptake in brown adipose tissue(BAT) can be a common cause of potentially misleading false-positive PET scans.The goal of this study was to study 18F-FDG uptake in cervical and supraclavicular regions and its characteristics with PET/CT.METHODSAll the PET/CT scans obtained at our institutionfrom July 2007 to January 2008 were retrospectively reviewed forincreased 18F-FDG uptake in BAT.The cases in which increased18F-FDG in cervical and supraclavicular regions was not localizedto a so -tissue mass or lymph node or muscle on the CT images,were included in this study.The following features were recorded:body weight,body mass index(BMI) and maximal standardizeduptake value(SUVmax).In these selected patients,the BAT uptake in other area of the body was also recorded.RESULTS PET/CT scans were obtained in 457 patients(259 males and 198 females).In all of the scans,cervical and supraclavicular BAT uptake was observed in 12 patients(2 males and 10 females) and was typically bilateral,symmetric and intense.The range of the SUVmax was 3.6~12.82(mean 6.9 ± 2.6).BAT uptake was more common in females than in males,showing a significant difference(P = 0.004).Although 18F-FDG uptake in BAT occurred more o en in underweight patients with low BMI,there was no difference in the body weight(P = 0.607) or BMI(P = 0.491) of these patients with hypermetabolic BAT compared with controls.CONCLUSION Hypermetabolic BAT uptake can be localized in cervical and supraclavicular regions with it occurring more commonly in females compared to males.Knowledge of this potential pitfall with PET/CT is important in improving diagnostic interpretation and accurate staging.Na Fang Yanli Wang Xinjian Cui Lei Zeng Lili Ma Xiumei Zhao Wei Zhao Qing Wang Shan Gao Wei Ding 2008Chinese Journal of Clinical Oncology2008,5,5:0

20Study on the reaction of 3-methyl-2-butenal and 3-methylbutanal with Cl atoms: kinetics and reaction mechanism显示文摘The reaction of Cl atoms with two C5aldehydes(3-methyl-2-butenal and 3-methylbutanal)were investigated by proton-transfer-reaction mass spectrum(PTR-MS)using smog chamber at 298±1 K and 760 Torr.A relative rate method was used to determine the rate constants of the title reactions with m-xylene and trans-2-butene as reference compounds:(3.04±0.18)×10^(-10)and(2.07±0.14)×10^(-10)cm^(3)/(molecule·sec)for 3-methyl-2-butenal and 3-methylbutanal,respectively.Additionally,the gas-phase products were also identified by PTR-MS,and the possible reaction mechanisms were proposed basing on the identified products.The detected gas-phase products are similar for two C5aldehydes reactions,mainly including small molecules of aldehydes,ketones and chlorinated aldehyde compounds.The atmospheric lifetimes(τ)calculated for 3-methyl-2-butenal(τ=7.0 hr,marine boundary layer(MBL))and 3-methylbutanal(τ=10.3 hr,MBL)according to the obtained rate constants.The results indicate that Cl atoms at MBL are competitive with OH radicals for the degradation contribution of C5aldehyde compounds.Bo Shi Weigang Wang Cici Fan Yuchan Zhang Zheng Sun Yanli Zeng Maofa Ge 2022Journal of Environmental Sciences2022,34,6:0
