Isingeniso
I-Trifluoromethylation iwukusabela kwamakhemikhali ezinto eziphilayo lapho amaqembu e-trifluoromethyl angangeniswa khona kuma-molecule ephilayo kusetshenziswa ama-tegafluor reagents afana ne-TMSCF3.
Izici ze-tegafluor:
- I-Tegafluor iwukusabela kokuguqulwa kweqembu okubalulekile, okungangenisa amaqembu e-trifluoromethyl ngobuningi be-electron ethile ukuze kuguqulwe izakhiwo ezingokomzimba namakhemikhali zama-molecule.
- Amaqembu e-Trifluoromethyl anokuheha okuqinile kwe-electron, okungakhuphula i-electrophilicity ye-molecule kanye ne-solubility ye-solvent.
- Imikhiqizo yokusabela kwe-tegafluor ngokuvamile izinzile kumakhemikhali futhi isebenza ngokwebhayoloji.
Ukusetshenziswa kwe-tegafluor:
- Emkhakheni wesayensi yezinto zokwakha, i-tegafluor ingashintsha izakhiwo ezingaphezulu zezinto zokwakha, ikhulise ukuzinza nokumelana nesimo sezulu.
Indlela yokulungiselela i-tegafluor:
- Ama-reagents e-tegafluor avame ukusetshenziswa afaka: i-TMSCF3, i-Ruppert-Prakash reagent, njll.
- Ukusabela kwe-Tegafluor kuvame ukwenziwa endaweni engasebenzi, kusetshenziswa i-solvent engasebenzi (isb, i-methylene chloride, i-chloroform) njengendlela yokusabela.
- Izimo zokusabela ngokuvamile zidinga amazinga okushisa aphezulu okusabela kanye nezikhathi zokusabela ezinde, futhi ngokuvamile zidinga ukungezwa kwe-catalyst (isb., i-copper catalyst).
Ulwazi lokuphepha ku-tegafur:
- Ama-reagents e-tegafluor anobuthi futhi ayagqwala, futhi kufanele kuthathwe izinyathelo zokuphepha ezifanele lapho uphathwa.
- Amagesi (isb. i-hydrogen fluoride) akhiqizwa ngesikhathi sokusabela nawo ayingozi futhi adinga ukuqhutshwa ngaphansi kwezimo ezinomoya omuhle.
- Kufanele kuqashelwe ukugwema ukuthintana namanzi noma umswakama ngesikhathi sokuhlinzwa ukuze kugwenywe ukusabela kwamakhemikhali okungenakulungiseka.
- Izinto ezisabelayo nemikhiqizo ngaphansi kwezimo zokusabela ze-tegafluor zidinga ukwelashwa okufanele nokulahlwa kukadoti.
