I-Trifluoromethanesulfonic anhydride, eyaziwa nangokuthi i-triflic anhydride, iyinhlanganisela yamakhemikhali enefomula₂O.
Yi-acid anhydride etholakala ku-triflic acid.
Le nhlanganisela iyi-electrophile eqinile, ewusizo ekwethuleni iqembu le-triflyl, i-CF₃SO₂.
I-Tf₂O efushanisiwe, i-triflic anhydride iyi-acid anhydride ye-acid triflic acid eqinile, i-CF₃SO₂OH.

I-Trifluoromethanesulfonic Anhydride iyi-electrophile enamandla esetshenziswa ekuhlanganiseni kwamakhemikhali ukwethulwa kweqembu le-triflyl.
I-Trifluoromethanesulfonic anhydride isetshenziselwa ukuguqula ama-phenols futhi imine ibe yi-triflic ester kanye neqembu le-NTf.I-electrophile enamandla esetshenziselwa ukwethulwa kweqembu le-triflyl ekuhlanganiseni kwamakhemikhali.Isebenza njenge-reagent ekulungiseleleni ama-alkyl kanye ne-vinyl triflates, kanye nokuhlanganiswa kwe-stereoelective kwabanikeli be-mannosazide methyl uronate.Isebenza njenge-catalyst ye-glycosylation enoshukela we-anomeric hydroxy ukulungisa ama-polysaccharides.
Isevisi esingayinikeza
1) Inkontileka esemthethweni ingasayinwa
2) Isivumelwano sokugcinwa kuyimfihlo singasayinwa
3) Isiqinisekiso sokubuyiselwa imali sezinsuku eziyisikhombisa
Okubaluleke nakakhulu: asikwazi ukunikeza umkhiqizo kuphela, kodwa isevisi yesixazululo sobuchwepheshe!
Singabakhiqizi, imboni yethu itholakala eShandong, kodwa futhi singakunikeza insizakalo eyodwa yokuthenga!
T/T(i-telex transfer), Western Union, MoneyGram, BTC(bitcoin), njll.
≤25kg: zingakapheli izinsuku ezintathu zokusebenza ngemuva kokutholwa kwenkokhelo.＞25kg: isonto elilodwa
Iyatholakala, singanikeza amasampula amancane mahhala ngenjongo yokuhlola ikhwalithi!
1kg isikhwama ngasinye fpr amasampula, 25kg noma 50kg isigubhu ngasinye, noma njengoba ubufuna.
Gcina isitsha sivalwe ngokuqinile endaweni eyomile, epholile futhi enomoya omuhle.
