Nhanganyaya
Trifluoromethylation is an organic chemical reaction umo trifluoromethyl mapoka anogona kuunzwa muma organic molecules achishandisa tegafluor reagents se TMSCF3.
Zvinhu zve tegafluor:
- Tegafluor iboka rakakosha rekushandura rekuita, iro rinogona kuunza mapoka e-trifluoromethyl ane imwe electron density kuti achinje chimiro chemuviri nemakemikari emamorekuru.
- Mapoka eTrifluoromethyl ane simba remagetsi rinokwezva, izvo zvinogona kuwedzera electrophilicity yemorekuru uye solubility ye solvent.
- Zvigadzirwa zve tegafluor reaction zvinowanzo gadzikana mumakemikari uye biologically inoshanda.
Kushandiswa kwe tegafluor:
- Mumunda wesainzi yemidziyo, tegafluor inogona kushandura nzvimbo yepasi yezvinhu, kuwedzera kugadzikana kwavo uye kuramba kwemamiriro ekunze.
Kugadzirira nzira ye tegafluor:
- Inowanzo shandiswa tegafluor reagents inosanganisira: TMSCF3, Ruppert-Prakash reagent, nezvimwe.
- Tegafluor reactions inowanzoitwa mumhepo inert, uchishandisa inert solvent (semuenzaniso, methylene chloride, chloroform) seyekuita svikiro.
- Mamiriro ekuita anowanzoda tembiricha yepamusoro uye nguva refu yekuita, uye kazhinji inoda kuwedzerwa kwechinhu chinokonzeresa (semuenzaniso, copper catalyst).
Ruzivo rwekuchengetedza pa tegafur:
- Tegafluor reagents ine muchetura uye inoparadza, uye matanho akakodzera anofanirwa kutorwa pakubata.
- Magasi (eg hydrogen fluoride) anogadzirwa panguva yekupindura ane njodzi zvakare uye anoda kushandiswa pasi pemhepo inofefetera.
- Chengetedzo inofanirwa kutorwa kudzivirira kusangana nemvura kana humidity panguva yekushanda kudzivirira kusinga gadziriswe kemikari.
- Reactants uye zvigadzirwa pasi pe tegafluor reaction mamiriro zvinoda kurapwa kwakakodzera uye kuraswa kwemarara.
