Pyridinium chlorochromate (PCC) yog ib qho tseem ceeb reagent nyob rau hauv cov organic synthesis siv feem ntau rau xaiv oxidation ntawm cawv kom muab carbonyl compounds.
Corey's reagent yog dab tsi siv rau?
Nws yog ib qho reagent hauv cov organic synthesis siv feem ntau rau oxidation ntawm cawv los ua carbonyls. Ntau yam sib txuas sib txuas tau paub nrog cov tshuaj zoo sib xws. PCC muab qhov zoo ntawm kev xaiv oxidation ntawm cawv rau aldehydes lossis ketones, qhov ntau lwm cov tshuaj reagents yog xaiv tsawg.
PCC yog dab tsi?
PCC yog tus neeg sawv cev oxidizing. Nws hloov cawv rau carbonyls, tab sis tsis muaj zog txaus los hloov cov cawv thawj rau hauv carboxylic acid. Nws tsuas yog hloov cov cawv thawj rau aldehydes, thiab cov cawv thib ob rau ketones. 1-pentanol yog thawj cawv yog li nws yuav hloov mus rau aldehyde pentanal.
PCC ua dab tsi rau lub diol?
PCC tsis yog-aqueous thiab tsis-acidic, tshem tawm cov xwm txheej raws li lub pov haum Diol yuav tsim. Yog li ntawd, qhov thib ob oxidation kauj ruam los ntawm ib qho aldehyde mus rau carboxylic acid yuav tsis tshwm sim.
Dab tsi yog qhov tsis zoo ntawm PCC?
PCC yog acidic dua PDC, tab sis cov kua qaub-labile tebchaw tuaj yeem oxidized nyob rau hauv muaj sodium acetate los yog lwm yam buffers xws li carbonates. Lwm qhov tsis zoo yog tsim cov khoom khov uas cuam tshuam cov khoom sib cais.
