Intshayelelo

I-2-Chloro-5-iodopyridine yi-organic compound.

 

I-2-Chloro-5-iodopyridine ineempawu ezibalulekileyo. Yikhompawundi enuka kamnandi enamaqela asebenzayo anje ngealkoholi kunye neeamines, ene-electrophilicity enamandla. Okwesibini, inokunyibilika okuphezulu kunye noxinzelelo lomphunga oluphantsi, kwaye inokubakho kwindawo eqinileyo okanye engamanzi kwiqondo lobushushu begumbi.

 

Ikhompawundi inoluhlu olubanzi lwezicelo kwiindawo ezininzi. Ihlala isetyenziswa njenge-reagent okanye i-catalyst kwi-organic synthesis reactions, umzekelo njenge-acid catalyst ye-esterification reactions. Isenokusetyenziswa nasekudityanisweni kwamayeza okubulala izitshabalalisi, ii-pigments, kunye nedayi.

 

Kukho iindlela ezininzi zokulungiselela i-2-chloro-5-iodopyridine. Indlela eqhelekileyo kukusabela i-2-chloro-5-aminopyridine kunye ne-thionyl iodide okanye i-hydrogen iodide ukuvelisa i-compound kwi-reaction. Iyakwazi ukulungiswa nge-iodination ye-2-chloro-5-bromopyridine.

 

Ulwazi lokhuseleko: I-2-chloro-5-iodopyridine yi-organic compound kunye neengozi ezithile. Xa usebenza, amanyathelo okhuseleko afana nokunxiba iiglavu zokhuselo, iiglasi, kunye nempahla yokhuselo iyafuneka. Kufuneka isetyenziswe kwiimeko zomoya kwaye ugweme ukuphefumla, ukungeniswa, okanye ukudibanisa nolusu. Kwimeko yokudibana okanye ukuphefumla ngempazamo, funa unyango olukhawulezileyo.
