Hoʻolauna

ʻO 3-(trifluoromethyl)pyridine, i ʻike ʻia ʻo 1-(trifluoromethyl)pyridine, he mea hoʻohuihui.

 

ʻAno maikaʻi:

3-(trifluoromethyl)pyridine he wai kala ʻole me ka ʻala ikaika. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, dimethylformamide, a me ka dimethyl sulfoxide.

 

E hoʻohana:

Hoʻohana nui ʻia ka 3-(trifluoromethyl) pyridine e like me nā catalysts, solvents a me nā reagents i ka synthesis organik. Hiki ke hoʻohana ʻia e like me ka boron chloride reagent i ka synthesis o nā waiʻona, nā waikawa, a me nā derivatives ester. Hiki ke hoʻohana ʻia e like me ka sodium hydroxide-catalyzed borate esterification reagent no nā aldehydes a me nā ketones.

 

Hanana:

Nui nā ala e hoʻomākaukau ai i ka 3- (trifluoromethyl) pyridine. ʻO ke ala maʻamau ka loaʻa ʻana o ka huahana ma ka hopena o pyridine a me trifluoromethylsulfonyl fluoride. Ua hoʻoheheʻe ʻia ka pyridine i loko o kahi mea hoʻoheheʻe etera, a laila hoʻohui mālie ʻia ka trifluoromethylsulfonyl fluoride. Hoʻokō pinepine ʻia nā pane ma nā mahana haʻahaʻa a koi i ka ea kūpono e pale aku ai i ka laha ʻana o nā kinoea ʻona.

 

ʻIke palekana: He wai ʻaʻa ia e hiki ke hana maʻalahi i ke ahi ke ʻike ʻia i kahi lapalapa ākea a i ʻole ka wela wela. He mea hoʻoheheʻe organik kekahi i loaʻa ka hopena hoʻonāukiuki i ka ʻili, nā maka, a me ka ʻōnaehana hanu. Pono e hoʻohana ʻia nā mīkina lima pale, nā maka aniani, a me nā mea hanu i ka wā o ka hana ʻana, a pono e hana ʻia ka hana ma kahi wahi hoʻoluʻu maikaʻi.
