1Environmentally benign chemical fixation of CO_(2) catalyzed by the functionalized ion-exchange resins显示文摘Basic ion-exchange resins,one kind of polystyryl-supported tertiary amine,were demonstrated to be highly efficient and recyclable catalysts for the fixation of carbon dioxide with aziridines under mild conditions,leading to the formation of 5-aryl-2-oxazolidinone with excellent regio-selectivities.Notably,neither solvents nor any additives were required,and the catalyst could be recovered by simple filtration and directly reused at least five times without significant loss of catalytic activity and selectivity.The present protocol has been applied to reactions of epoxides/propargyl amines with CO_(2)/CS2.This solvent-free process thus represents environmentally friendly catalytic conversion of CO_(2) into value-added chemicals and may have potential in various continuous flow reactors in industry.LIU AnHua HE LiangNian PENG ShiYong PAN ZhongDa WANG JingLun GAO Jian 2010Science China Chemistry2010,53,7:2
2Green Catalysis for Three-Component Reaction of Carbon Dioxide, Propargylic Alcohols and Nucleophiles显示文摘ZHOU Zhihua XIA Shumei HE Liangnian 2018物理化学学报2018,34,8:2
3Polyethylene glycol radical-initiated aerobic propargylic oxidation in dense carbon dioxide显示文摘The selective aerobic oxidation of alkynes to correspondingα,β-acetylenic ketones was achieved in polyethylene glycol/dense CO2/O2 biphasic system without any catalyst or additive.The effects of reaction parameters,e.g.temperature,CO2 pressure,PEG molecular weight and loading on the reaction were carefully examined.Moreover,various substrates worked well in the presence of PEG 1000 under 5 MPa of CO2 and 2 MPa of O2 at 100℃for 12 to 24 h and acceptable yield and selectivity could be obtained in most cases.Preliminary mechanistic investigations were also discussed.Zhenfeng Diao Bin Li Bing Yu Anhua Liu Liangnian He 2013Journal of Energy Chemistry2013,22,3:1
4Selective and high yield synthesis of dimethyl carbonate directly from carbon dioxide and methanol显示文摘 He Liangnian Yasuda H 2002Green Chemistry2002,,4:1
5Oxidation of aromatic sulfides with molecular oxygen:Controllable synthesis of sulfoxides or sulfones显示文摘The recent development of selective oxidation of aromatic sulfides with molecular oxygen was highlighted.The sulfoxides and sulfones could be obtained by simply switching the reaction media,i.e.,bis(2-butoxyethyl)ether(BBE)or poly(ethylene glycol)dimethyl ether(PEGDME).The application of the high-boiling-point polyether as an initiator and green media can eliminate the need of large quantities of additives and volatile solvents.This strategy represents an economic and eco-friendly method that could find potential applications.Lili Tang Kejie Du Bing Yu Liangnian He 2020Chinese Chemical Letters2020,31,12:1
6Self-Neu- tralizing in situ Acidic COJHzO System for Aerobic Oxidation of Alcohols Catalyzed by TEMPO Functionalized Imidazolium Salt/NaNO2 显示文摘Miao Chenxia He Liangnian Wang Jinglun 2010JOrgChem2010,75,1:1
7Nonhalogen catalysts for propylene carbonate synthesis from CO2 under supercritical conditions显示文摘Yasuda Hiroyuki He Liangnian Sakakura Toshiyasu 2006Applied Catalysis A: General2006,298,:1
8New Procedure for Recycling Homogeneous Catalyst: Propylene Carbonate Syn- thesis Under Supercritical CO2 Conditions 显示文摘He Liangnian Yasuda H Sakakura T 2003Green Chem2003,5,1:1
9Ionic Liquids in Energy and Environment显示文摘Ionic liquids (ILs) have received a great deal of attention because they are less-volatile, less-flammable, have low toxicity and unique solubility for many organic and inorganic materials, and these properties allow them to be used in various fields of sustainable sciences. Remarkable progress in the science of ILs has been accomplished during the past two decades;the number of publications of ILs reached more than 90,000 since 1999 to be present [1]. ILs are nowwell recognized as essential players in the fields of environmental benign synthesis, catalysts, extraction, electrochemistry, and biotechnology, and they also attract much attention as a key technology to promote the spread of renewable energy.Toshiyuki Itoh Masayoshi Watanabe Liangnian He 2019Green Energy & Environment2019,4,2:0
10Study on Synthesis and Herbicidal Activity of Heterocyclic Compounds Containing P-P Bond显示文摘N,N’-diphenylurea reacted with phosphorus trichloride and phenyl dicklorophospbane giving theheterocyclic compounds 1 and 2 with a direct phosphorus-phosphorus bond (P-P bond ), respectively. The newcompounds were characterized by elementary analysis, NMR and IR spectra. The results or preliminary bioassay showed that these heterocycles possess selective herbicidal activity at 1.5 kg/hm2.He Liangnian Zhuo Renxi Cai Lei Lu Alhong 1998Wuhan University Journal of Natural Sciences1998,3,1:0
