Ukupakisha Iqela II
I-2,3-Dichloro-5,6-Dicyano-1,4-Benzoquinone (DDQ) (i-CAS: 84-58-2) isetyenziswe njenge-oxidizing agent, ngokukodwa kwi-synthesis ye-steroid.
I-DDQ ineentlobo ngeentlobo zezicelo.I-DDQ yi-arhente yokukhusela ii-ketals, ii-acetals, kunye ne-thioacetals.Yinto eluncedo yokudlulisa i-electron kwi-synthesis ye-quinolones kunye ne-oxidizing agent esetyenziselwa ukwenza i-steroids.Ukongeza, i-DDQ isetyenziswa kunye ne-Ph3P ukwenza i-1,2-benzisoxazoles.
I-DDQ i-reagent eyomeleleyo ye-oxidation, esetyenziswa ngokubanzi kwi-dehydrogenation ye-compounds, ngokukodwa kwi-steroid compounds.Inokhetho oluhle kwaye luyimfuneko ye-oxidation reagent kwishishini le-steroid.Ngokunzulu kophando, ngokuthe ngcembe kufunyaniswa ukuba i-DDQ ibonisa ithemba lesicelo esilungileyo kwiimpendulo ezininzi zezinto eziphilayo.Ngokomzekelo, i-oxidation ekhethiweyo yee-alcohols, i-oxidation kwindawo ye-benzyl ye-ring ye-aromatics, ukubunjwa kweebhondi ze-carbon-carbon, ukwakheka kwee-carbon heterobonds, ii-Cyclization Reactions, ukukhuselwa kunye nokukhusela, kunye nokunye okunjalo.Isetyenziswa njengama-pharmaceutical intermediates, ngokukodwa njenge-dehydrogenation agents kwi-steroid hormone compounds.
I-DDQ isetyenziswa ngokubanzi ngakumbi kwiimpendulo zezinto eziphilayo, kwaye iindawo zayo zokusetyenziswa ziyanda.Ukuphuhliswa kwemimandla emitsha yesicelo, ngakumbi i-oxidative coupling cyclization reaction, yeyona nto iphambili yophuhliso lwe-DDQ kuphando lwesicelo se-organic reactions.
I-DDQ (i-CAS: 84-58-2) iphendula ngamanzi ukuze ikhuphe i-hydrogen cyanide (HCN) enetyhefu kakhulu.Iqondo lobushushu eliphantsi kunye ne-acidity ebuthathaka yonyusa ukuzinza kwe-DDQ.Kufuneka igcinwe kwindawo eyomileyo.
