Ukupakisha Iqembu II
I-2,3-Dichloro-5,6-Dicyano-1,4-Benzoquinone (DDQ) (i-CAS: 84-58-2) isetshenziswa njenge-oxidizing agent, ikakhulukazi ekuhlanganiseni kwe-steroid.
I-DDQ inezinhlelo zokusebenza ezihlukahlukene.I-DDQ iyi-ejenti yokuvikela yama-ketals, ama-acetal, nama-thioacetals.Kuyi-reagent ewusizo yokudlulisa i-electron yokuhlanganiswa kwama-quinolones kanye ne-oxidizing esetshenziselwa ukuhlanganisa ama-steroid.Ukwengeza, i-DDQ isetshenziswa ne-Ph3P ukuze kuhlanganiswe i-1,2-benzisoxazoles.
I-DDQ iyi-reagent eqinile ye-oxidation, esetshenziswa kakhulu ekukhipheni ama-compounds, ikakhulukazi kuma-steroid compounds.Inokukhethwa okuhle futhi iyi-reagent edingekayo ye-oxidation embonini ye-steroid.Ngokujula kocwaningo, kancane kancane kutholakala ukuthi i-DDQ ikhombisa amathuba amahle okusebenza ekuphenduleni okuningi kwemvelo.Isibonelo, i-oxidation ekhethiwe yotshwala, i-oxidation endaweni ye-benzyl yendandatho enephunga elimnandi, ukwakheka kwebhondi ye-carbon-carbon, ukwakheka kwama-heterobond e-carbon, ukusabela kwe-Cyclization, ukuvikelwa nokuvinjelwa, nokunye okunjalo.Isetshenziswa njengama-intermediate emithi, ikakhulukazi njengama-ejenti e-dehydrogenation we-steroid hormone compounds.
I-DDQ iya ngokuya isetshenziswa kabanzi ekuphenduleni kwe-organic, futhi izinkambu zayo zohlelo ziyakhula.Ukuthuthukiswa kwezinkambu zohlelo olusha, ikakhulukazi ukusabela kokuhlanganisa i-oxidative coupling cyclization, kuwumkhuba oyinhloko wokuthuthuka we-DDQ ocwaningweni lohlelo lokusebenza lokusabela kokuphilayo.
I-DDQ (CAS: 84-58-2) iphendula ngamanzi ukuze ikhiphe i-hydrogen cyanide (HCN) enobuthi obukhulu.Izinga lokushisa eliphansi kanye nendawo ene-asidi ebuthakathaka inyusa ukuzinza kwe-DDQ.Idinga ukugcinwa esimweni esomile.
