3,5-Dibromo-2-fluoropyridine ke motsoako oa manyolo o nang le motsoako oa lik'hemik'hale C5H2Br2FN. E latelang ke tlhaloso ea sebopeho sa eona, tšebeliso, tlhahiso le tlhaiso-leseling ea polokeho:
Tlhaho:
- 3,5-Dibromo-2-fluoropyridine ke motsoako o tiileng o nang le ponahalo e tšoeu ea kristale.
-Ntho ea eona e qhibilihang ke 74-76 ℃, 'me ntlha ea eona e belang ke 238-240 ℃.
-Ha e qhibilihe ka metsing ka mocheso oa kamore, empa e ka qhibiliha ka har'a li-solvents tse ling tse kang ether le ethanol.
Sebelisa:
- 3,5-Dibromo-2-fluoropyridine ke motsoako oa bohlokoa oa bohareng o sebelisoang ka ho pharaletseng liketsong tsa organic synthesis.
-E ka sebelisoa e le thepa e tala bakeng sa lisebelisoa tsa organic photovoltaic, hape e ka sebelisoa ho lokisa meriana, dae le chefo e bolaeang likokoanyana.
Mokhoa oa ho itokisa:
- 3,5-Dibromo-2-fluoropyridine e ka lokisoa ke karabelo ea iodide ea pyridine le bromide ea cuprous.
- Qala ka ho qhaqha cuprous bromide le pyridine iodide ka dimethyl sulfoxide mocheso oa kamore ho etsa reactant, ebe butle-butle eketsa silver fluoride dropwise ka mocheso o tlaase, 'me qetellong mocheso ho fihlela karabelo e phethoa.
Lintlha tsa Tšireletseho:
- 3,5-Dibromo-2-fluoropyridine e halefisa letlalo le mahlo, 'me mehato ea tšireletso e lokela ho lefshoa ha e kopana.
-Ela hloko moea o motle oa moea ha u sebelisa motsoako ona.
-E senyeha ka mocheso o phahameng o tla hlahisa likhase tse kotsi, 'me hoa hlokahala ho qoba ho pepesehela malakabe a bulehileng kapa libaka tse phahameng tsa mocheso.
-E boloke ka mokhoa o tiisitsoeng 'me u qobe ho kopana le li-oxidants le li-acid tse matla ho qoba liketso tse kotsi.
