Selelekela
2-Bromo-5-(trifluoromethyl)pyridine (eo hape e tsejoang e le BTFP) ke motsoako oa tlhaho. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mokhoa oa ho lokisa le tlhaiso-leseling ea polokeho:
Boleng:
- Ponahalo: E tšoeu e tiileng
- Boima ba molek'hule: 206.00 g / mol
- Sollubility: BTFP e qhibiliha habonolo ka har'a metsoako ea tlhaho (mohlala, joala, ethers, ketone) empa ha e qhibilihe ka metsing.
Sebelisa:
- E le motsoako oa mahareng: BTFP e sebelisoa haholo ho lokiseng li-intermediate tsa organic synthesis, joalo ka metsoako ea pyridine, metsoako e nkhang hamonate, joalo-joalo.
- Joaloka ligand: BTFP e ka sebelisoa e le ligand bakeng sa li-complexes tsa tšepe 'me e kenya letsoho liketsong tse fapa-fapaneng tsa catalytic le ho lokisetsa lisebelisoa tse sebetsang.
- Joalo ka reagent: BTFP e bapala karolo ea bohlokoa ho organic synthesis, joalo ka coupling reaction, substitution reaction, le karabelo ea phokotso.
Mokhoa:
2-Bromo-5-(trifluoromethyl)pyridine e ka etsoa ka mehato e latelang:
1. Hlakola 2-amino-5-(trifluoromethyl)pyridine ka mokelikeli o loketseng oa lintho tse phelang, tse kang joala kapa ketone.
2. Kenya metsoako ea bromine (mohlala, hydrogen bromide, methyl bromide).
3. Etsa karabelo ka mocheso o nepahetseng le maemo a susumetsang.
4. Sefa sehlahisoa 'me u etse crystallization le tlhoekiso.
Lintlha tsa Tšireletseho:
- BTFP e ka tiisa kapa ea khanya ka mocheso o tlase, ka kopo boloka mocheso oa kamore 'me u qobe kristale.
- Apara liatlana tse sireletsang le likhalase nakong ea ts'ebetso ho qoba ho kopana le letlalo le mahlo.
- Qoba ho hema lerōle kapa mouoane oa eona, kaha BTFP e ka 'na ea e-ba le phello e halefisang tseleng ea ho hema.
- Sheba bukana ea tšireletso e amehang ha u sebelisa kapa u tšoara BTFP, 'me u lahle litšila le lihlapolli ka nepo.
