N-Bromosuccinimide/NBS/CAS: 128-08-5

Whakamahinga

Ko te N-Bromosuccinimide, e whakarapopototia ana ko te NBS, he matū tioata angiangi, he mā ki te mā-parauri te tae. Ka wairewa i roto i te acetone, tetrahydrofuran, te N,N-dimethylformamide, te dimethyl sulfoxide, me te acetonitrile, he paku wairewa i roto i te wai me te waikawa acetic, ā, kāore e wairewa i roto i te ether, te hexane, me te carbon tetrachloride. He maha ngā wā ka whakamahia te NBS i roto i ngā tauhohenga bromination radical kore utu o ngā rōpū allyl me te benzyl; ngā tauhohenga bromination electrophilic o ngā ketone, ngā pūhui kakara, ngā pūhui heterocyclic rānei; ngā tauhohenga hydroxylation, etherification, me te lactonization o ngā olefins. He tairongo te NBS ki te makuku, ā, me penapena ki roto i te pouaka whakamātao. I te wā e whakamahia ana, me karo te manawa, te pā rānei ki te kiri, ā, i te nuinga o te wā ka whakahaerehia i roto i te pūwero hau me te mahi hau pai.

Hei matū hei tautuhi i ngā waipiro tuatahi, tuarua, me te tuatoru. Ka taea te whakamahi hei hanga rongoā bromoacetonitrile. I roto i te umanga patu pepeke, ka whakamahia hei hanga thiabendazole, ā, ka taea hoki te whakamahi hei tiaki hua, hei patu paturopi, hei ārai harore, me ētahi atu. He rauemi mata hanga rauropi, hei whakahaere i ngā tauhohenga bromination iti-pūngao, ā, ka whakamahia hoki i roto i te hanga tāpiri rapa me ngā rongoā. Ka taea te whakamahi hei hanga bromoacetonitrile mō te rongoā. I roto i te umanga patu pepeke, ka whakamahia hei hanga thiabendazole, ā, ka taea hoki te whakamahi hei tiaki hua, hei patu paturopi, hei ārai harore. Ka whakamahia hei matū hei tautuhi i ngā waipiro tuatahi, tuarua, me te tuatoru, me te tāpiri mō ngā hua rapa, ā, ka whakamahia hoki i roto i te hanga rauropi. He matū brominating nui i roto i te hanga rauropi. I roto i te umanga rongoā, ka whakamahia pinepine hei matū brominating i roto i te hanga paturopi, pērā i te hanga cefaloram. Hanga rauropi. Bromination o ngā olefins. Te waikura o te etanoru ki ngā aldehydes me ngā ketones. Te whakahāngaitanga o ngā aldehyde ki ngā waikawa bromo. He kaihopu bromine maha-mahi. Ka whakamahia i roto i te tauhohenga whakahāngaitanga o te tryptophan, engari he iti pea te taumata whakahāngaitanga o ngā toenga tyrosine, histidine, me te methionine. Ka taea hoki te whakamahi mō te whakarerekētanga o ngā rōpū ribosomal thiol. He kaihopu bromine whānui. I te aroaro o te AIBN, ka taea te whakahāngaitanga o ngā silyl ethers ki ngā aldehyde. He matū bromine whānui; ka whakamahia mō te whakahāngaitanga o te tryptophan, ahakoa he iti ake pea ngā toenga whakahāngaitanga tyrosine, histidine, me te methionine; ka whakamahia mō te whakarerekētanga rōpū o ngā rōpū ribosomal thiol; i te aroaro o te AIBN, ka whakahāngaitia ngā silyl ethers ki ngā aldehyde.
