Daim ntawv thov
4-Acetamidobenzenesulfonyl azide/p-ABSA (CAS: 2158-14-7) yog ib qho tseem ceeb ntawm cov tshuaj intermediates.
Nws cov ntawv thov tseem ceeb suav nrog:
1. 4-Acetamidobenzenesulfonyl azide yog tshwj xeeb sulfonyl azide reagent rau diazotization nyob rau hauv kws tshuaj intermediate synthesis.
2. p-ABSA yog siv los npaj diazo tebchaw rau cyclization, insertion thiab nias heterocyclization tshwm sim.
3. 4-Acetamidobenzenesulfonyl azide ua haujlwm ua haujlwm reagent hauv kev tshawb fawb tshuaj zoo rau nitrogen- uas muaj cov qauv molecular.
Cia
1. Khaws kom nruj thiab khaws cia hauv qab 20℃hauv qhov tsaus tsaus kom tsis txhob muaj teeb pom kev zoo -induced decomposition ntawm azide moiety.
2. nruj me ntsis kom tsis txhob muaj kev sib txhuam ntawm kev sib txhuam, kev cuam tshuam thiab kub kub kom tsis txhob tawg tawg.
3. Khaws cais los ntawm cov ntsev hnyav hlau, cov ntxhia hauv cov kua qaub thiab muaj zog txo cov neeg ua haujlwm.
Cov ntaub ntawv kev nyab xeeb
1. Tsis txhob nqus cov hmoov av crystalline; hnav tawg- tsom iav pov thawj, plua plav daim npog qhov ncauj thiab hnab looj tes tiv thaiv tshuaj.
2. Tsis txhob nqos cov khoom; yaug qhov muag thiab tawv nqaij nrog dej txias kom txaus tam sim ntawd tom qab sib cuag.
3. Tshem tawm cov khib nyiab pov tseg thiab cov khib nyiab pov tseg kom ua raws li cov txheej txheem pov tseg tshuaj lom neeg azide.
Cov txiaj ntsig ntawm Kev Siv
1. Kev hloov pauv diazo nruab nrab haum rau kev xaiv hloov dua siab tshiab ntawm cov khoom siv methylene substrates.
2. Acetamide pab txhim kho kev ruaj ntseg thiab txo qhov kev pheej hmoo ntawm decomposition piv nrog tosyl azide unsubstituted.
3. Zoo solubility nyob rau hauv anhydrous polar organic solvents kom yooj yim kuaj cov khoom ua haujlwm.
