Isingeniso

I-2-Chloro-5-iodopyridine iyinhlanganisela yezinto eziphilayo.

 

I-2-Chloro-5-iodopyridine inezakhiwo ezibalulekile. Kuyinhlanganisela enamakha enamaqembu asebenzayo afana notshwala nama-amine, ane-electrophilicity eqinile. Okwesibili, inokuncibilika okuphezulu kanye nomfutho we-vapor ophansi, futhi ingaba khona esimweni esiqinile noma esiwuketshezi ekamelweni lokushisa.

 

I-compound inezinhlelo eziningi ezihlukene emikhakheni eminingi. Ivamise ukusetshenziswa njenge-reagent noma njenge-catalyst ku-organic synthesis reactions, isibonelo njenge-acid catalyst yokusabela kwe-esterification. Ingasetshenziswa futhi ekuhlanganiseni izibulala-zinambuzane, ama-pigments, namadayi.

 

Kunezindlela eziningana zokulungiselela i-2-chloro-5-iodopyridine. Indlela evamile iwukusabela i-2-chloro-5-aminopyridine nge-thionyl iodide noma i-hydrogen iodide ukukhiqiza inhlanganisela ekuphenduleni. Ingabuye ilungiswe nge-iodination ye-2-chloro-5-bromopyridine.

 

Ulwazi lokuphepha: I-2-chloro-5-iodopyridine iyinhlanganisela yemvelo enobungozi obuthile. Lapho usebenza, izinyathelo zokuphepha ezinjengokugqoka amagilavu ​​okuzivikela, izibuko, nezingubo zokuzivikela ziyadingeka. Kufanele isetshenziswe ezimeni ezinomoya futhi ugweme ukuhogela, ukungenwa, noma ukuthintana nesikhumba. Uma uthintana ngephutha noma uhogele umoya, funa usizo lwezokwelapha ngokushesha.
