Ojiji

N-Bromosuccinimide, nke a na-akpọkarị NBS, bụ ihe kristal dị mma nke na-acha ọcha ruo na ọcha n'agba. Ọ na-agbaze na acetone, tetrahydrofuran, N,N-dimethylformamide, dimethyl sulfoxide, na acetonitrile, nke na-agbaze ntakịrị na mmiri na acetic acid, ọ naghịkwa agbaze na ether, hexane, na carbon tetrachloride. A na-ejikarị NBS eme ihe na mmeghachi omume bromination free radical nke otu allyl na benzyl; mmeghachi omume bromination electrophilic nke ketones, ihe ndị na-esi ísì ụtọ, ma ọ bụ ihe ndị na-eme ka heterocyclic dị na ya; mmeghachi omume hydroxylation, etherification, na lactonization nke olefins. NBS na-enwe mmetụta maka mmiri mmiri ma ekwesịrị ịchekwa ya na friji. N'oge ojiji, a ga-ezere iku ume ma ọ bụ kọntaktị na akpụkpọ ahụ, a na-arụkwa ya n'ime mkpuchi anwụrụ ọkụ na arụmọrụ ikuku dị mma.

A na-eji ya dị ka ihe na-eme ka mmadụ mata mmanya mbụ, nke abụọ, na nke atọ. A na-ejikwa ya emepụta ọgwụ bromoacetonitrile. N'ụlọ ọrụ ọgwụ ahụhụ, a na-eji ya emepụta thiabendazole ma nwee ike iji ya mee ihe dị ka ihe na-eme ka mkpụrụ osisi dị mma, ihe na-eme ka ọ dị ọcha, na ihe na-eme ka ọ dị ọcha, wdg. Ọ bụ ihe e ji emepụta ihe ndị sitere n'okike, nke a na-eji achịkwa mmeghachi omume bromination dị ala, a na-ejikwa ya eme ihe na mmepụta ihe mgbakwunye roba na ọgwụ. A na-ejikwa ya emepụta bromoacetonitrile maka ọgwụ. N'ụlọ ọrụ ọgwụ ahụhụ, a na-eji ya emepụta thiabendazole ma nwee ike iji ya mee ihe dị ka ihe na-eme ka mkpụrụ osisi dị mma, ihe na-eme ka ọ dị ọcha, na ihe na-eme ka ọ dị ọcha. A na-eji ya eme ihe dị ka ihe na-eme ka ọ dị ọcha maka ịchọpụta mmanya mbụ, nke abụọ, na nke atọ na ihe mgbakwunye maka ngwaahịa roba, a na-ejikwa ya eme ihe na ihe ndị sitere n'okike. Ọ bụ ihe dị mkpa maka brominating na ihe ndị sitere n'okike. N'ụlọ ọrụ ọgwụ, a na-ejikarị ya eme ihe dị ka ihe na-eme ka ọ dị ọcha na ihe ndị sitere n'okike, dịka ihe na-eme ka ọ dị ọcha, dịka ihe na-eme ka ọ dị ọcha. Oxidation nke aldehydes na bromo - acids. Ihe na-arụ ọrụ nke brominating dị iche iche. A na-eji ya eme ihe na mmeghachi omume oxidation nke tryptophan, mana ọkwa oxidation nke tyrosine, histidine, na methionine residents nwere ike ịdị obere. Enwere ike iji ya mee mgbanwe nke ribosomal thiol groups. Ọ bụ ihe na-arụ ọrụ brominating zuru ụwa ọnụ. N'ihu AIBN, enwere ike itinye silyl ethers ka ọ bụrụ aldehydes. Ọ bụ ihe na-arụ ọrụ brominating zuru ụwa ọnụ; ejiri ya mee ihe maka oxidation nke tryptophan, ọ bụ ezie na enwere ike ịnwe tyrosine, histidine, na methionine residents ruo obere oge; ejiri ya mee mgbanwe otu nke ribosomal thiol groups; n'ihu AIBN, a na-eme ka silyl ethers ka ọ bụrụ aldehydes.
