CAS: 1599466-87-1|Sphos Pd G4

SPhos Pd G4, tseem hu ua methanesulfonate (2-dicyclohexylphosphino-2',6'-dimethoxybiphenyl)(2'-methylamino-1,1'-biphenyl{10}}yl)palladium (II), yog palladium catalyst feem ntau siv nyob rau hauv cov organic synthetic chemistry. Nws yog siv los txhawb kev sib txuas sib txuas xws li Suzuki-Miyaura coupling cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv Heck.

Khoom:

1. Palladium hlau chaw: Raws li kev hloov pauv hlau, palladium (II) yog siv dav hauv cov organic chemistry thiab catalytic cov tshuaj tiv thaiv, tshwj xeeb tshaj yog nyob rau hauv kev sib txuas sib txuas.
2. Ligand system: Nws muaj cov qauv biphenyl nrog ob lub methoxy hloov ntawm ib lub nplhaib biphenyl thiab ib pawg dicyclohexylphosphine txuas rau lwm lub nplhaib biphenyl. Kev tsim cov ligand no tuaj yeem txhim kho cov kev ua haujlwm catalytic thiab kev xaiv ntawm palladium.
4. Methanesulfonic acid: Qhov no yog ib hom sulfonic acid, feem ntau yog siv los ua anion ib feem ntawm txoj kev.

Kev siv:

1. Nws muaj cov ntawv thov tseem ceeb hauv palladium-catalyzed cross-coupling cov tshuaj tiv thaiv (xws li Suzuki-Miyaura cov tshuaj tiv thaiv, Buchwald-Hartwig amination cov tshuaj tiv thaiv, thiab lwm yam). Nws tuaj yeem txhawb kev tsim cov carbon-carbon lossis carbon-nitrogen bonds.
2. Catalytic kev ua tau zoo: Vim nws cov qauv ligand tshwj xeeb, qhov sib xyaw no muaj kev ua haujlwm siab catalytic thiab xaiv tau thiab tuaj yeem ua rau mob me me.
3. Kev ruaj ntseg: Cov qauv tsim ntawm ligand tuaj yeem txhim kho qhov chaw palladium zoo thiab txo qhov deactivation ntawm palladium catalyst thaum lub sij hawm cov tshuaj tiv thaiv.

1. Cia tej yam kev mob: Nws feem ntau yuav tsum tau muab cia rau hauv ib tug qhuav, lub teeb-pov thawj ib puag ncig kom tsis txhob decomposition nyob rau hauv high kub thiab noo tej yam kev mob.
2. Kev nyab xeeb: Zoo li feem ntau cov palladium tebchaw, qhov sib xyaw no yuav tsum tsis txhob sib cuag ncaj qha rau ntawm daim tawv nqaij thiab qhov muag, thiab cov khoom siv tiv thaiv tsim nyog yuav tsum hnav thaum ua haujlwm.

Gnee Chemical muaj pab pawg tswj xyuas kev tshawb fawb tau zoo, muaj zog R & D lub zog, kev tswj cov khoom lag luam zoo thiab cov kev pabcuam zoo tom qab muag. Cov yam ntxwv no tsis tsuas yog ua kom zoo thiab ruaj khov ntawm peb cov khoom, tab sis kuj yeej qhov kev ntseeg siab thiab kev txhawb nqa ntawm peb cov neeg siv khoom.
