Nhanganyaya
Iyo organic compound ine molecular formula C≡H∞BrFN, ine fluorine atomu, methyl boka uye bromine atomu inotsiviwa papyridine mhete.
Zvakasikwa:
yakasimba, ine chepfu uye inogumbura. Inonyungudika muorganic solvents senge ethanol uye dimethylformamide patembiricha yekamuri, uye inogona hydrogen bond nemamwe mahydrogen bond anogamuchira (semuenzaniso, madoro).
Shandisa:
Inowanzoshandiswa sechinhu chekutanga kana chepakati mune organic synthesis reactions. Inogona kushandiswa mukugadzirira kwemishonga yemishonga, mishonga yezvipembenene uye mamwe organic compounds. Huwandu hwayo hwekushandisa hunosanganisira tsvakiridzo yemishonga, makemikari synthesis uye zvinhu sainzi.
Kugadzirira nzira:
Nzira yekugadzirira ye fluorination inogona kuwanikwa ne benzyl bromination uye fluorination. Kutanga, benzyl compound (4-methylpyridine) inoshandiswa ne benzylidene bromide kuti ibudise bromobenzyl compound (2-bromo-4-methylpyridine). Mushonga uyu unobva waitwa ne hydrofluoric acid kugadzira inoenderana nefluorinated product (phosphonium).
Zvekuchengetedza
ine chepfu, inofanira kutora matanho ekudzivirira akakodzera. Dzivisa kusangana neganda, maziso uye kufema turakiti panguva yekushanda. Inofanirwa kushandiswa munzvimbo ine mhepo inofefetera zvakanaka, uye pfeka magirazi ekudzivirira akakodzera, magurovhosi uye masks. Chengetedza kure nemoto uye oxidizing agents, uye dzivisa kuita nemamwe makemikari. Kana akafumurwa kana kufemerwa, tsvaga rubatsiro kuna chiremba nekukurumidza.
