Hordhac
Waa iskudhis organic ah oo leh caanaha molecular C≡H∞BrFN, kaas oo leh atom fluorine, koox methyl ah iyo atom bromine ah oo lagu beddelay giraanta pyridine.
Dabeecadda:
waa mid adag, sun ah oo xanaaq badan. Waxay ku milmi kartaa dareerayaasha dabiiciga ah sida ethanol iyo dimethylformamide heerkulka qolka, waxayna ku xidhi kartaa hydrogen iyo qaar aqbalayaasha dammaanadda hydrogen (tusaale, alkolada).
Isticmaal:
Inta badan waxaa loo isticmaalaa sida walxo bilow ah ama dhexdhexaad ah falcelinta isku-dhafka dabiiciga ah. Waxaa loo isticmaali karaa diyaarinta daawooyinka, sunta cayayaanka iyo xeryahooda kale ee organic. Codsiyada kala duwan ee ay bixiso waxaa ka mid ah cilmi baarista dawooyinka, isku dhafka kiimikada iyo sayniska agabka.
Habka Diyaarinta:
Habka diyaarinta ee fluorination waxaa lagu gaari karaa by bromination benzyl iyo fluorination. Marka hore, xarun benzyl (4-methylpyridine) ayaa lagu falceliyaa benzylidene bromide si loo soo saaro xarun bromobenzyl (2-bromo-4-methylpyridine). Xaruntan ayaa markaa lagu falcelinayaa aashitada hydrofluoric si ay u soo saarto badeecada fluorinated ee u dhiganta (phosphonium).
Macluumaadka Badbaadada:
waa sun, waa in la qaadaa tallaabooyin ilaalin oo habboon. Ka fogow taabashada maqaarka, indhaha iyo mareenka neef-mareenka xilliga shaqada. Waa in lagu isticmaalo meel hawo fiican leh, oo xidho muraayadaha ilaalinta habboon, galoofyada iyo maaskaro. Ka fogee dabka iyo walxaha oksaydhiyaha ah, kana fogow falcelinta kiimikooyinka kale. Haddii ay soo baxdo ama la nuugo, u raadi talo caafimaad isla markiiba.
