Silver trifluoromethanesulfonate, makwaara dị ka AgOTf, bụ ike na vasatail reagent eji na dị iche iche chemical mgbanwe.Ọ bụ na klas nke metal triflates, nke dị ukwuu bara uru na organic njikọ n'ihi na ha Lewis acidity na ike rụọ ọrụ substrates.One nke isi ngwa nke silver trifluoromethanesulfonate bụ dị ka a catalyst na organic Jeremaya mere.Ọ nwere ike ikwado mgbanwe dị iche iche, gụnyere carbon-carbon bond na-eme mmeghachi omume, dị ka Friedel-Crafts alkylation na mmeghachi omume acylation, yana carbon-nitrogen bonding mmeghachi omume, dị ka N-acylation nke amines ma ọ bụ njikọ nke amides.Ọdịdị Lewis acidic nke AgOTf na-enyere ya aka ịhazi ya na ihe ndị bara ụba na electron, na-eduga na ịgbalite nkekọ kemịkalụ kpọmkwem na ikwado mmeghachi omume achọrọ.Ọrụ catalytic ya bara uru karịsịa na njikọ nke ọgwụ, agrochemicals, na ezigbo kemịkal.AgOTf dịkwa uru n'ịkwalite nhazigharị na mmeghachi omume cyclization.Ọ nwere ike kpalite mmeghachi omume nhazigharị dị iche iche, dị ka nhazigharị Beckmann, nke na-atụgharị oximes ka ọ bụrụ amides ma ọ bụ esters, ma ọ bụ nhazigharị nke mmanya na-egbu egbu iji mepụta ogige carbonyl.Na mgbakwunye, ọ nwere ike inye aka na mmeghachi omume cyclization, na-enyere aka guzobe ogige cyclic nwere sistemụ mgbanaka dị mgbagwoju anya.Àgwàetiti Lewis acidic nke AgOTf na-ekere òkè dị mkpa na mmeghachi omume ndị a site n'ịkwado usoro nhazi nke njikọ dị mkpa na usoro cyclization. Ọzọkwa, a na-eji ọlaọcha trifluoromethanesulfonate mee ihe na ịgbalite nkekọ carbon-hydrogen (CH).Ọ nwere ike ịgbalite njikọ CH n'akụkụ otu ndị na-arụ ọrụ, dị ka na ịgbalite aromatic CH bond ma ọ bụ ịgbalite njikọ allylic ma ọ bụ benzylic CH.Nkwalite a na-enye ohere maka ịrụ ọrụ na-esote nke njikọ CH, na-eduga na nguzobe nke carbon-carbon ọhụrụ ma ọ bụ carbon-heteroatom bond.Usoro a, nke a maara dị ka CH activation, bụ ubi na-eto ngwa ngwa na njikọ nke organic ma na-enye ụzọ dị mma iji nweta ihe mgbagwoju anya molecular .A na-ejikarị ya na obere nha, dị ka ọnụọgụ catalytic, n'ihi nnukwu mmeghachi omume ya.Ekwesịrị iji nlezianya rụọ ọrụ na mpaghara ikuku nke ọma na iji chebe reagent ka ọ ghara ikpughe na mmiri. Na nchịkọta, ọlaọcha trifluoromethanesulfonate (AgOTf) bụ ihe bara uru reagent na ihe na-akpali akpali na organic synthesis.Ọdịdị ya nke Lewis acidic na-enyere ya aka ịgbalite mkpụrụ ndụ, kwalite nhazigharị na mmeghachi omume cyclization, ma mee ka njikọ CH rụọ ọrụ, na-eduga na nguzobe nke mkpụrụ ndụ ihe dị mgbagwoju anya.Agbanyeghị, a ga-akpachapụ anya mgbe ị na-ejikwa ma na-echekwa AgOTf iji hụ na nkwụsi ike ya wee gbochie mmeghachi omume achọghị.
