稀土元素在有机合成中的应用姓名：陈亚运专业：应用化学学号：156061203班级：化工2班一种新型F-引发脱氢及氧化脱氰基的荧光探针阴离子探针的识别原理如下：基于C-H键的阴离子探针以往报道的N-H键对阴离子识别主要是基于静电作用，氢键作用，金属配位效应，随后发现一些列的咪唑类化合物对阴离子的识别主要是基于C-H键的静电相互作用，如引入合适的推拉电子基团能够使受体中的C-H键，表现出强于N-H键。Inorg.Chem.2006,45,8205−8210.我们设计如下试验方案与路线：稀土元素的特点：1、价电子在4f轨道上，性质类似碱金属和碱土金属。2、镧系元素常常显示相似的化学性质。3、氧化态主要是＋3价4、性质上的差异主要是离子半径的逐渐变化。5、属于硬酸。6、不符合18电子规则，配位数很高。合成方法1、三价稀土化合物的合成LnCl3+2RM→R2LnCl可以转化为稀土氢化物、烷(芳)基化物、烷(芳)氧基化物、烯丙基化合物等。对于稀土化合物没有CO、烯烃络合物的报道，1994年第一次报道了烯烃卡宾络合物(A.J.Arduengo,etal.J.Am.Chem.Soc.,1994,116,7927.)2、两价稀土化合物的合成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应用(一)、在有机合成中的应用1、氢化，稀土氢化物作催化剂2、氢胺化3、醛的二聚、三聚反应4、异氰酸苯酯的二聚、三聚反应5、稀土烷氧基参与的反应6、其它反应在高分子合成中的应用1、催化烯烃聚合2、催化甲基丙烯酸甲酯的聚合3、催化己内酯的开环聚合4、催化丙烯腈的聚合相关文献[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,JosipTišljar.Chapter10–HazardsofMinerals–RocksandSustainableDevelopment.IntroductiontoMineralogyandPetrology,2014:305–323.[15]ShuangLIU,XiaodongWU,DuanWENG,RuiRAN.Ceria-basedcatalystsforsootoxidation:areview.JournalofRareEarths,2015,June:567–590.[15]郑华德.谭砂砾.尹衍升.李传校.张敬超机动车尾气净化用纳米稀土催化剂展望-现代技术陶瓷2003(1).
