Hoʻolauna

ʻO ka Trifluoromethylation kahi hopena kemika organik kahi e hiki ai ke hoʻokomo ʻia nā pūʻulu trifluoromethyl i loko o nā molekala organik me ka hoʻohana ʻana i nā reagents tegafluor e like me TMSCF3.

 

Nā waiwai o tegafluor:

- ʻO Tegafluor kahi hopena hoʻololi hui koʻikoʻi, hiki iā ia ke hoʻolauna i nā pūʻulu trifluoromethyl me kahi ʻano electron density e hoʻololi i nā waiwai kino a me nā molekala.

- Loaʻa i nā hui Trifluoromethyl ka huki electron ikaika, hiki ke hoʻonui i ka electrophilicity o ka mole a me ka solubility o ka solvent.

- ʻO nā huahana o ka pane tegafluor ka mea maʻamau paʻa a me ka hana biologically.

 

Nā hoʻohana o ka tegafluor:

- Ma ke kahua o ka ʻepekema waiwai, hiki i ka tegafluor ke hoʻololi i nā waiwai o ka ʻili o nā mea, hoʻonui i ko lākou kūpaʻa a me ka pale ʻana i ka wā.

 

ʻO ke ʻano o ka hoʻomākaukau ʻana o tegafluor:

- Hoʻohana pinepine ʻia nā reagent tegafluor: TMSCF3, Ruppert-Prakash reagent, etc.

- Hoʻohana mau ʻia nā hopena Tegafluor i loko o ka lewa inert, me ka hoʻohana ʻana i kahi mea hoʻoheheʻe inert (e laʻa, methylene chloride, chloroform) ma ke ʻano he ʻano hana.

- Pono nā kūlana hoʻololi i ka wela o ka hopena a me ka manawa ʻoi aku ka lōʻihi, a koi pinepine i ka hoʻohui ʻana i kahi catalyst (e laʻa, copper catalyst).

 

ʻIke palekana ma tegafur:

- He mea ʻawaʻawa a ʻino nā mea hoʻohui ʻo Tegafluor, a pono e mālama pono i ka wā e lawelawe ai.

- ʻO nā kinoea (e laʻa me ka hydrogen fluoride) i hana ʻia i ka wā o ka hopena he mea pōʻino nō hoʻi a pono e hana ʻia ma lalo o nā kūlana ea.

- Pono e mālama ʻia e pale aku i ka pili ʻana me ka wai a i ʻole ka haʻahaʻa i ka wā o ka hana e pale aku i nā hopena kemika hiki ʻole ke hoʻololi.

- Pono nā reactants a me nā huahana ma lalo o nā kūlana hoʻohālikelike tegafluor i ka mālama kūpono a me ka hoʻolei ʻōpala.
