Kupu Whakataki
Ko te 3-(trifluoromethyl)pyridine, e mohiotia ana ko 1-(trifluoromethyl)pyridine, he pūhui waro.
Kounga:
Ko te 3-(trifluoromethyl)pyridine he wai kore tae me te kakara kaha. He wairewa i roto i te maha o nga whakarewa pararopi penei i te waihano, te dimethylformamide, me te dimethyl sulfoxide.
Whakamahia:
Ko te 3-(trifluoromethyl)pyridine e whakamahia whānuitia ana hei whakakōkī, whakarewa me te reagents i roto i te whakahiato waro. Ka taea te whakamahi hei reagent boron chloride i roto i te whakahiatotanga o te waipiro, te waikawa, me nga hua ester. Ka taea hoki te whakamahi hei reagent konutai hydroxide-catalyzed borate esterification reagent mo te aldehydes me te ketones.
Tikanga:
He maha nga huarahi hei whakarite i te 3-(trifluoromethyl)pyridine. Ko te tikanga noa ko te whiwhi i te hua ma te tauhohenga o te pyridine me te trifluoromethylsulfonyl fluoride. I rewa te pyridine i roto i te whakarewa ether, katahi ka ata taapirihia te trifluoromethylsulfonyl fluoride. I te nuinga o te wa ka mahia nga tauhohenga ki te iti o te mahana, me te hiahia kia pai te hau kia kore ai e horapa nga hau paitini.
Mōhiohio Haumaru: He wai muramura ka ngawari te ahi ina pa ana ki te mura o te mura, te wera nui ranei. He whakarewa pararopi hoki tera ka pa te kino ki te kiri, nga kanohi, me te punaha manawa. Me mau nga karapu whakamarumaru, nga karaehe, me nga taputapu manawa i te wa e mahi ana, me mahi te mahi i roto i te waahi pai te hau.
