稀土化學(xué)2-陳亞運(yùn)

稀土元素在有機(jī)合成中的應(yīng)用姓名：陳亞運(yùn)專業(yè)：應(yīng)用化學(xué)學(xué)號：156061203班級：化工2班一種新型F-引發(fā)脫氫及氧化脫氰基的熒光探針陰離子探針的識別原理如下：基于C-H鍵的陰離子探針以往報(bào)道的N-H鍵對陰離子識別主要是基于靜電作用，氫鍵作用，金屬配位效應(yīng)，隨后發(fā)現(xiàn)一些列的咪唑類化合物對陰離子的識別主要是基于C-H鍵的靜電相互作用，如引入合適的推拉電子基團(tuán)能夠使受體中的C-H鍵，表現(xiàn)出強(qiáng)于N-H鍵。Inorg.Chem.2006,45,8205?8210.我們設(shè)計(jì)如下試驗(yàn)方案與路線：稀土元素的特點(diǎn)：1、價(jià)電子在4f軌道上，性質(zhì)類似堿金屬和堿土金屬。2、鑭系元素常常顯示相似的化學(xué)性質(zhì)。3、氧化態(tài)主要是＋3價(jià)4、性質(zhì)上的差異主要是離子半徑的逐漸變化。5、屬于硬酸。6、不符合18電子規(guī)則，配位數(shù)很高。合成方法1、三價(jià)稀土化合物的合成LnCl3+2RM→R2LnCl可以轉(zhuǎn)化為稀土氫化物、烷(芳)基化物、烷(芳)氧基化物、烯丙基化合物等。對于稀土化合物沒有CO、烯烴絡(luò)合物的報(bào)道，1994年第一次報(bào)道了烯烴卡賓絡(luò)合物(A.J.Arduengo,etal.J.Am.Chem.Soc.,1994,116,7927.)2、兩價(jià)稀土化合物的合成⑴、Ln+NH3(l)+HCp→Cp2Ln⑵、Ln+C5Me5H(l)→(C5Me5)2Ln⑶、LnX2+2RM→R2Ln⑷、R2LnX+Na→R2Ln稀土化合物在均相催化中的應(yīng)用(一)、在有機(jī)合成中的應(yīng)用1、氫化，稀土氫化物作催化劑2、氫胺化3、醛的二聚、三聚反應(yīng)4、異氰酸苯酯的二聚、三聚反應(yīng)5、稀土烷氧基參與的反應(yīng)6、其它反應(yīng)在高分子合成中的應(yīng)用1、催化烯烴聚合2、催化甲基丙烯酸甲酯的聚合3、催化己內(nèi)酯的開環(huán)聚合4、催化丙烯腈的聚合相關(guān)文獻(xiàn)[1]ElisaAlonso,AndrewM.Sherman,TimothyJ.Wallington,MarkP.Everson,FrankR.Field,RichardRoth,andRandolphE.Kirchain*.EvaluatingRareEarthElementAvailability:ACasewithRevolutionaryDemandfromCleanTechnologies[J].Environ.Sci.Technol.,2012,46(6),pp3406–3414.[2]YuukiMochizuki,NaotoTsubouchi,andKatsuyasuSugawara.SelectiveRecoveryofRareEarthElementsfromDycontainingNdFeBMagnetsbyChlorination[J].ACSSustainableChem.Eng.,2013,1(6),pp655–662.[3]XiaoyueDuandT.E.Graedel.GlobalIn-UseStocksoftheRareEarthElements:AFirstEstimate[J].Environ.Sci.Technol.,2011,45(9),pp4096–4101.[4]ClintonW.Noack,DavidA.Dzombak,andAthanasiosK.Karamalidis.RareEarthElementDistributionsandTrendsinNaturalWaterswithaFocusonGroundwater[J].Environ.Sci.Technol.,2014,48(8),pp4317–4326.[5]GeorgeG.Zaimes,BerlynJ.Hubler,ShuoWang,andVikasKhanna.EnvironmentalLifeCyclePerspectiveonRareEarthOxideProduction[J].ACSSustainableChem.Eng.,2015,3(2),pp237–244.[6]FengxiaGeng,RenzhiMa,andTakayoshiSasaki.Anion-ExchangeableLayeredMaterialsBasedonRare-EarthPhosphors:UniqueCombinationofRare-EarthHostandExchangeableAnions[J].Acc.Chem.Res.,2010,43(9),pp1177–1185.[7]WenLi,RongjinHuang,WeiWang,JieTan,YuqiangZhao,ShaopengLi,ChuanjunHuang,JunShen,andLaifengLi.EnhancedNegativeThermalExpansioninLa1–xPrxFe10.7Co0.8Si1.5CompoundsbyDopingtheMagneticRare-EarthElementPraseodymium[J].Inorg.Chem.,2014,53(11),pp5869–5873.[8]PhilipL.Verplanck,EdwardT.Furlong,JamesL.Gray,PatrickJ.Phillips,RuthE.WolfandKathleenEsposito.EvaluatingtheBehaviorofGadoliniumandOtherRareEarthElementsthroughLargeMetropolitanSewageTreatmentPlants.Environ[J].Sci.Technol.,2010,44(10),pp3876–3882.[9]JelleH.Rademaker,RenéKleijn,andYongxiangYang.RecyclingasaStrategyagainstRareEarthElementCriticality:ASystemicEvaluationofthePotentialYieldofNdFeBMagnetRecycling[J].Environ.Sci.Technol.,2013,47(18),pp10129–10136.[10]TakaomiD.Yokoyama,ToshihiroSuzuki,YoshiakiKon,andTakafumiHirata.DeterminationsofRareEarthElementAbundanceandU-PbAgeofZirconsUsingMultispotLaserAblation-InductivelyCoupledPlasmaMassSpectrometry[J].Anal.Chem.,2011,83(23),pp8892–8899.[11]JessicaWahsnerandMichaelSeitz.SynthesisofInertHomo-andHeterodinuclearRare-EarthCryptates[J].Inorg.Chem.,2015,54(20),pp9681–9683.[12]LarryD.Claxton.Thehistory,genotoxicity,andcarcinogenicityofcarbon-basedfuelsandtheiremissions.Dieselandgasoline.MutationResearch/ReviewsinMutationResearch.2015,January–March:30–85.[13]AliBumajdada,JulianEastoeb,AshaMathewa.Ceriumoxidenanoparticlespreparedinself-assembledsystems.AdvancesinColloidandInterfaceScience,2009,March–June:56–66.[14]S.K.Haldar,JosipTi?ljar.Chapter10–HazardsofMinerals–RocksandSustainableDevelopment.IntroductiontoMineralogyandPetrology,2014:305–323.[15]ShuangLIU,XiaodongWU,DuanWENG,RuiRAN.Ceria-basedcatalystsforsootoxidation:areview.JournalofRareEarths,2015,June:567–590.[15]鄭華德.譚砂礫.尹衍升.李傳校.張敬超機(jī)動車尾氣凈化用納米稀土催化劑展望-現(xiàn)代技術(shù)陶瓷2003(1).
