Isicelo:

I-Potassium Bis (trimethylsilyl) i-amide (i-0.5M Isisombululo kwi-Toluene) (ngokuqhelekileyo ifinyeziwe njenge-KHMDS) (i-CAS: i-40949-94-8) isiseko esinamandla, esingeyo-nucleophilic kunye ne-pKa esondeleyo ye-26 (thelekisa ne-lithium diisopropylamide, kwi-36 ).Ifumaneka ngokurhweba njengento eqinileyo kwaye njengesisombululo kwiintlobo ezahlukeneyo zokunyibilikisa (umz. THF, 2Me-THF, toluene, kunye neMTBE).Ii-reagents ezifanayo ziquka i-lithium bis (trimethylsilyl) amide (LiHMDS) kunye ne-sodium bis (trimethylsilyl) amide (NaHMDS).Isiseko esomeleleyo se-non-nucleophilic megasteric.I-Pharmaceutical intermediates, esetyenziselwa ukuveliswa kwe-synthetic cephalosporins.I-KHMDSsisixhobo sekhemikhali esisetyenziswa kwi-chromatography yolwelo olulungiselelayo olusebenza kakhulu.Isetyenziselwa ukwenza ii-complexes ezizinzileyo kunye ne-potassium, ezize zihlulwe yikholomu.I-KHMDS ikwasetyenziswa kuphando lwe-biochemical kunye ne-asymmetric synthesis catalyst.I-KHMDS sisiseko esomeleleyo esisetyenziswa kwi-alkylation carbonyl compounds.I-KHMDS isetyenziselwa ukulungiswa kwe-5-Azacytidine, ichiza le-antineoplastic.Kwakhona kusetyenziswe ekulungiseleleni i-β3-AR i-agonists esetyenziswe kwi-anti-stress formulations.Ikwasetyenziswa njenge-reagent ekulungiseleleni izakhiwo ze-lanthanide eziqeshwe kwiimpendulo ezikhethiweyo zebhayisikile.
