2,3-Dichloro-5,6-Dicyano-1,4-Benzoquinone (DDQ) (CAS: 84-58-2) imagwiritsidwa ntchito ngati oxidizing agent, makamaka mu steroid synthesis.
DDQ ili ndi ntchito zosiyanasiyana.DDQ ndi chitetezo choteteza ma ketals, acetals, ndi thioacetals.Ndiwothandiza ma elekitironi kutumiza reagent pa kaphatikizidwe wa quinolones ndi oxidizing wothandizila ntchito synthesize steroids.Kuphatikiza apo, DDQ imagwiritsidwa ntchito ndi Ph3P kupanga 1,2-benzisoxazoles.
DDQ ndi reagent yamphamvu ya okosijeni, yomwe imagwiritsidwa ntchito kwambiri pochotsa hydrogenation ya mankhwala, makamaka kwa mankhwala a steroid.Ili ndi kusankha bwino ndipo ndiyofunikira kwambiri pakupanga ma steroid.Ndikukula kwa kafukufukuyu, pang'onopang'ono zimapezeka kuti DDQ ikuwonetsa chiyembekezo chabwino chogwiritsa ntchito pamachitidwe ambiri achilengedwe.Mwachitsanzo, kusankha makutidwe ndi okosijeni mowa, makutidwe ndi okosijeni pa malo benzyl wa mphete onunkhira, mapangidwe carbon-carbon zomangira, mapangidwe mpweya heterobond, Cyclization Reactions, chitetezo ndi deprotection, ndi zina zotero.Amagwiritsidwa ntchito ngati mankhwala apakatikati, makamaka ngati dehydrogenation agents for steroid hormone compounds.
DDQ imagwiritsidwa ntchito mochulukirachulukira pamachitidwe achilengedwe, ndipo magawo ake akuchulukirachulukira.Kukula kwa magawo atsopano ogwiritsira ntchito, makamaka oxidative coupling cyclization reaction, ndiye njira yayikulu yachitukuko cha DDQ pakugwiritsa ntchito kafukufuku wama organic reaction.
DDQ (CAS: 84-58-2) imachita ndi madzi kutulutsa poizoni wa hydrogen cyanide (HCN).Malo otsika komanso ofooka acidic amawonjezera kukhazikika kwa DDQ.Ayenera kusungidwa mu youma boma.
