Intshayelelo yemveliso
N,N-Diethylaniline CAS:91-66-7
I-N,N-diethylaniline lulwelo olutyebileyo olutyebileyo olungasetyenziselwa ukulungisa idayi ze-azo, iidayi ze-triphenylmethane, njl. njl
indlela yokwenziwa
Dissolve dppe (1 mg, 0.0025 mmol) kwi-nBu2O eyomileyo (1 mL) kwaye ungeze i-Karstedt catalyst (29 μL, 0.0025 mol) kwityhubhu yeSchlenk phantsi kwe-argon atmosphere. Emva kokuvuselela umxube wemizuzu eyi-10, i-PhSiH3 (247 μL, 2.0 mmol) yongezwa. I-Aniline (45.6 μL, 0.5 mmol), n-hexadecane (50 μL) njengomgangatho wangaphakathi, kunye ne-CH3ChemicalbookCO2H (63 μL, 1.1 mmol) zongezwa ngoko nangoko, zaza zaxutywa kwiqondo lobushushu legumbi iiyure ezili-18. Ekugqityweni, umxube uhlanjululwe nge-ethyl acetate (15 mL), ucinywe ngokucophelela nge-NaOH yamanzi (isisombululo se-3M; 5 mL), kwaye ugxininise kwiqondo lokushisa kwe-3 h. Umxube obangelwayo ukhutshwe nge-ethyl acetate (amaxesha amathathu), kwaye i-organic layers edibeneyo yomiswa phezu kwe-anhydrous MgSO4. Isigaba sezinto eziphilayo sahluzwa, sagxininiswa, kwaye sahlanjululwa nge-silica gel ikholamu yechromatography (n-hexane / ethyl acetate umxube) ukunika i-N, N-diethylaniline.
Indawo yosetyenziso
Ingasetyenziselwa ukulungiselela i-azo dyes, i-triphenylmethane dyes, njl njl. Kwakhona ingundoqo ebalulekileyo yokudibanisa iziyobisi kunye nabaphuhlisi befilimu yombala, kwaye ukusetyenziswa kwayo kubanzi kakhulu.
