Cov Ntawv Thov
2 {- diphenylphephino {}}}}}}}} {} {}}}}}}}}} {}}}}}} Nws pabcuam ua ib qho kev tsis khi lus hais txog ob qho tib si phosphine thiab ib qho chaw pub dawb rau cov khoom siv hluav taws xob thiab cov chaw sib txuas ntawm cov chaw hlau. Cov kab ke no yog ib qho tseem ceeb txheej txheem ntawm buchwald-}}}}}}}}}}, heck, thiab buchwald-hartwal amination. Cov kev tawm tsam no yog qhov tseem ceeb yog kev ua cov pa roj carbon-carbon thiab carbon-nitrogen daim ntawv cog lus nyob rau hauv synthesis ntawm cov tshuaj, agnchemicals, thiab siab cov ntaub ntawv agnic. Nws cov muaj zog hlau-khi muaj peev xwm thiab hluav taws xob-peev xwm kuj ua rau nws muaj txiaj ntsig zoo, thiab carbonination cov tshuaj tiv thaiv thiab xaiv tau zoo yog qhov tseem ceeb.
Cov txiaj ntsig
Qhov txiaj ntsig tseem ceeb ntawm 2 {- dlheylphosphapino {{}}}}}}}}}}}}}}}}} (n, Qhov sib xyaw ua ke ntawm phosphine pab pawg thiab cov kev sib txuas lus hluav taws xob muaj zog uas muaj zog cuam tshuam nrog kev sib cuam tshuam nrog kev ua kom muaj zog thiab kev xaiv tau zoo. Nws cov steeler txwv txwv tsis pub ua rau cov tshuaj tua kab, cia rau kev tiv thaiv ntev ntev thiab dav dav substrate thev taus. Ib qho ntxiv, no lashal txhim kho cov tshuaj tiv thaiv nyob rau hauv cov mob me thiab minimizes qhov kev tsim ntawm kev tsis muaj txiaj ntsig, ua rau nws zoo tagnrho rau ob qho tib si kev siv khoom. Lub peev xwm zoo rau kev hloov kho hluav taws xob los ntawm kev hloov kho cov txheej txheem txuas ntxiv txuas ntxiv nws siv hauv kev tsim cov kev hloov pauv tshwj xeeb rau kev hloov pauv tshwj xeeb.
Tag
2 {- diphenylphephino {}}}}}}} pa hluav taws xob, sib txuas nrog hluav taws xob, ruaj khov, thiab ua haujlwm. Nws lub luag haujlwm tseem ceeb hauv kev hla dhau kev sib txuas thiab hydrogenation cov kev hloov pauv, txhawb kev nce qib hauv cov tshuaj, cov ntaub ntawv kawm paub, thiab kev tshawb fawb ntsuab. Los ntawm kev ua haujlwm siab, xaiv, thiab kev sib sau ua ke, cov compound no tseem muaj cov khoom siv hluavtaws thiab muaj kev siv tshuaj.
