Cov khoom tsis sib xws: muaj zog oxidizing tus neeg sawv cev
5-bromo-2-chloropyrimidine yog me ntsis alkaline, insoluble hauv dej tab sis soluble hauv cov organic solvents, suav nrog methylene chloride thiab chloroform. Vim tias tsis muaj cov khoom siv hluav taws xob ntawm pyrimidine, chlorine atoms hauv nws cov qauv tuaj yeem ua rau dechlorination ua haujlwm pab pawg cov tshuaj tiv thaiv nyob rau hauv kev tawm tsam ntawm nucleophiles, ntau nucleophiles muaj xws li cawv, amines thiab chemicalbooks. Nyob rau hauv lub xub ntiag ntawm ib tug nucleophile, oxygen los yog nitrogen atoms nyob rau hauv lub nucleophile tua cov chlorine atoms nyob rau hauv 5-bromo-2-chloropyrimidine, tsim intermediates uas yog nrog los ntawm cleavage thiab recombination tshua. Tsis tas li ntawd, bromine atoms ntawm lub nplhaib pyrimidine tuaj yeem dhau los ua ntau yam kev sib txuas nrog cov txheej txheem reagent thiab organic zinc reagent nyob rau hauv qhov kev txiav txim ntawm kev hloov hlau.
