Isingeniso

I-5-(4-bromophenyl)-4,6-dichloropyrimidine iyinhlanganisela yemvelo. Izici: I-5-(4-bromophenyl)-4,6-dichloropyrimidine iyinhlanganisela eqinile enokubukeka okumhlophe okukhazimulayo. Ayincibiliki kalula ezingeni lokushisa elijwayelekile. Ukusetshenziswa: Le nhlanganisela ivame ukusetshenziswa njenge-intermediate kuma-pesticides. Ukulungiselela: Indlela yokulungiselela i-5-(4-bromophenyl)-4,6-dichloropyrimidine ihlanganisa ukuqala ngokwakha i-4-bromophenyl-5-chloro-1-methylpyrimidine, bese kusetshenziswa i-copper cyanide njenge-catalyst ukwenza ukusabela kwe-nucleophilic substitution, ukushintsha i-athomu ye-chlorine esekhuleni le-pyrimidine nge-athomu ye-bromine ngokusebenzisa i-zinc. Ulwazi Lokuphepha: Le nhlanganisela iyi-organobromide futhi kufanele iphathwe ngokucophelela. Uma uyisebenzisa, gqoka amagilavu amelana namakhemikhali, izibuko zamehlo, nezingubo zokuzivikela. Gwema ukuthinta isikhumba, ukuhogela, noma ukugwinya. Uma kukhona umthombo womlilo, kungase kukhiqizwe amagesi ayingozi. Qinisekisa ukuthi kunomoya ohamba kahle ngesikhathi sokuphatha nokugcina.
