2,3-Dichloro-5,6-Dicyano-1,4-Benzoquinone (DDQ) (CAS: 84-58-2) yog siv los ua oxidizing tus neeg sawv cev, tshwj xeeb tshaj yog nyob rau hauv steroid synthesis.
DDQ muaj ntau yam kev siv.DDQ yog tus neeg saib xyuas kev tiv thaiv rau ketals, acetals, thiab thioacetals.Nws yog ib qho tseem ceeb ntawm kev hloov pauv hluav taws xob reagent rau kev sib txuas ntawm quinolones thiab tus neeg sawv cev oxidizing siv los ua ke steroids.Tsis tas li ntawd, DDQ yog siv nrog Ph3P los ua ke 1,2-benzisoxazoles.
DDQ yog ib qho muaj zog oxidation reagent, uas yog dav siv nyob rau hauv lub dehydrogenation ntawm cov tebchaw, tshwj xeeb tshaj yog rau steroid tebchaw.Nws muaj kev xaiv zoo thiab yog ib qho tseem ceeb oxidation reagent hauv kev lag luam steroid.Nrog rau qhov kev tshawb fawb tob zuj zus, nws maj mam pom tias DDQ qhia tau hais tias muaj kev cia siab rau daim ntawv thov zoo hauv ntau cov tshuaj tiv thaiv organic.Piv txwv li, xaiv oxidation ntawm cawv, oxidation ntawm benzyl txoj hauj lwm ntawm lub nplhaib aromatic, tsim ntawm carbon-carbon bonds, tsim ntawm carbon heterobonds, Cyclization Reactions, tiv thaiv thiab deprotection, thiab lwm yam.Siv ua tshuaj intermediates, tshwj xeeb tshaj yog cov tshuaj dehydrogenation rau cov tshuaj steroid hormones.
DDQ tau siv ntau thiab ntau dua hauv cov tshuaj tiv thaiv organic, thiab nws daim ntawv thov teb kuj nce ntxiv.Txoj kev loj hlob ntawm daim ntawv thov tshiab, tshwj xeeb tshaj yog cov oxidative coupling cyclization cov tshuaj tiv thaiv, yog lub ntsiab txoj kev loj hlob ntawm DDQ nyob rau hauv daim ntawv thov kev tshawb fawb ntawm cov organic tshuaj.
DDQ (CAS: 84-58-2) reacts nrog dej kom tso tawm cov tshuaj lom hydrogen cyanide (HCN).Qhov kub thiab qis acidic ib puag ncig ua rau muaj kev ruaj ntseg ntawm DDQ.Yuav tsum tau muab cia rau hauv lub xeev qhuav.
