Tetrabutylammonium iodide, nke a makwaara dị ka TBAI, bụ reagent a na-ejikarị eme ihe na mmeghachi omume kemịkal dị iche iche.Otu n'ime ngwa TBAI kacha adọrọ mmasị na nke a na-amụ n'ọtụtụ ebe bụ iji ya na njikọ nke azides.Mana kedu usoro dị n'azụ nzaghachi a, oleekwa otu TBAI si etinye aka na ya?
Usoro nzaghachi nke TBAI dị mgbagwoju anya ma tinye ọtụtụ usoro isi.N'ozuzu, mmeghachi omume a na-agụnye n'ọnọdụ nke ọgbọ hypoiodite sitere na TBAI na onye na-emeghachi omume nke a maara dị ka TBHP.Nke a hypoiodite ahụ na-emeghachi omume na ngwakọta carbonyl ka ọ bụrụ etiti nke na-emesịa azide.N'ikpeazụ, a na-emegharị hypoiodite ọzọ site na oxidation.
Nzọụkwụ mbụ na usoro mmeghachi omume gụnyere ọgbọ nke hypoiodite sitere na TBAI na TBHP.Nke a bụ nzọụkwụ dị oke egwu n'ihi na ọ na-amalite mmeghachi omume site n'inye ụdị iodine dị mkpa maka carbonyl oxidation na-esote.Hypoiodate na-emeghachi omume nke ukwuu ma nwee ike ịkwalite ọtụtụ mmeghachi omume kemịkal dị iche iche, gụnyere halogenation na oxidation.
Ozugbo e guzobere hypoiodite, ọ na-emeghachi omume na ngwakọta carbonyl iji mepụta etiti.A na-agbazi etiti a site na iji imide reagent, nke na-agbakwunye atom nitrogen abụọ na molekul ahụ wee "na-arụ ọrụ" ya maka mmeghachi omume ọzọ.N'oge a, TBAI ejezuola ebumnuche ya na ọ dịghịzi mkpa na mmeghachi omume.
Nzọụkwụ ikpeazụ na usoro ahụ gụnyere ịmaliteghachi hypoiodite.A na-enweta nke a site na oxidation site na iji co-reactants dị ka hydrogen peroxide.Ịmeghachi hypoiodite dị oké egwu n'ihi na ọ na-enye ohere ka mmeghachi omume na-aga n'ihu na-agba ọsọ ma na-emepụta azides ọzọ.
N'ozuzu, usoro nzaghachi TBAI mara mma nke ukwuu ma dịkwa mma.Site n'ịmepụta hypoiodite na ọnọdụ na iji ya oxidize ogige carbonyl, TBAI na-enyere ọgbọ nke azides aka nke ga-esi ike ma ọ bụ agaghị ekwe omume ịmepụta.Ma ị bụ onye na-ahụ maka kemist na-arụ ọrụ na ụlọ nyocha nyocha ma ọ bụ onye na-emepụta ihe na-achọ imepụta ihe ọhụrụ, TBAI nwere ọtụtụ ihe ọ ga-enye.Gbalịa ya taa!
