TRIMETHYLSULFOXONIUM KLORIDE CAS:5034-06-0

Trimethylsulfoxonium chloride waxay u adeegtaa sidii falgal kala duwan oo ku jira isku-darka dabiiciga ah, gaar ahaan falgalka oksaydhka Swern ee loogu beddelayo aldehydes ama ketones. Isku-darkani wuxuu u shaqeeyaa sidii qayb muhiim ah habka oksaydhka Swern, oo ay weheliso oxalyl chloride iyo dimethylsulfoxide, taasoo awood u siinaysa oksaydheynta hufan iyo xulashada ee alkolada aasaasiga ah iyo kuwa sare ee aldehydes iyo ketones. Isticmaalka trimethylsulfoxonium chloride ee habka oksaydhka Swern wuxuu bixiyaa faa'iidooyin sida xaaladaha falcelinta khafiifka ah, wax-soo-saarka sare, iyo is-waafajinta kooxo kala duwan oo shaqeynaya, taasoo ka dhigaysa qalab qiimo leh oo ku jira isku-darka molecules-ka dabiiciga ah ee adag. Intaa waxaa dheer, trimethylsulfoxonium chloride wuxuu helaa codsi ahaan wakiil methylating ah oo ku jira kiimikada dabiiciga ah, taasoo u oggolaanaysa methylation-ka nucleophiles-ka kala duwan xaaladaha khafiifka ah. Reagent-kani wuxuu fududeyn karaa soo bandhigidda kooxaha methyl-ka ee isku-dhafka dabiiciga ah, taasoo awood u siinaysa isku-darka alaabada methyl-ka kala duwan ee leh qaab-dhismeedyo iyo sifooyin loo habeeyay. Intaa waxaa dheer, trimethylsulfoxonium chloride waxaa loo isticmaalaa diyaarinta α-chloroketones iyo α-bromoketones, oo ah dhexdhexaadiyayaal qiimo leh oo ku jira isku-darka dabiiciga ah si loo sameeyo isbeddello dheeraad ah iyo soo saarista. Kiimikada daawada iyo helitaanka daawada, trimethylsulfoxonium chloride waxaa loo isticmaali karaa isku-darka dhexdhexaadiyeyaasha daawada iyo isku-darka bioactive. Iyadoo lagu darayo reagent-kan wadooyinka synthetic-ga ah, cilmi-baarayaashu waxay heli karaan noocyo kala duwan oo isku-dhafan oo leh hawlo daawo oo suurtagal ah, taasoo suurtogalinaysa sahaminta musharixiinta cusub ee daroogada iyo horumarinta daawooyinka cusub. Awoodda isku-dhafka ah ee wax ka beddelka qaab-dhismeedka molecular-ka iyo fududeynta falcelinta muhiimka ah ee organic-ga waxay gacan ka geysataa naqshadeynta iyo hagaajinta molecules-ka leh saamaynta bayoolojiga ee la rabo iyo sifooyinka daaweynta. Guud ahaan, trimethylsulfoxonium chloride waxay door muhiim ah ka ciyaartaa isku-darka organic-ga, iyadoo siinaysa kiimikooyinka synthetic-ga qalab qiimo leh oo loogu talagalay isbeddellada sida oksaydhka, methylation-ka, iyo maaraynta kooxda shaqaynaysa. Kala-duwanaanshaheeda, xaaladaha falcelinta fudud, iyo iswaafajinta substrates-ka kala duwan waxay ka dhigaysaa reagent qiimo leh sanduuqa qalabka ee kiimikooyinka dabiiciga ah iyo cilmi-baarayaasha ka shaqeeya helitaanka daawada, kiimikada daawada, iyo isku-darka kiimikada.
