Kev siv
Phenylosohydroxy tosylate ua hauj lwm ua tus oxidant siv nyob rau hauv cov synthesis ntawm ntau cov organic sib xyaw. Piv txwv li, nws ua rau ligand-dawb, palladium-cataly-catalyzed heck-type cov kev sib txuas. Nws tuaj yeem siv los npaj carbodiimides los ntawm lub cev qhuav dej thiab sulfidation ntawm thioouras. Ib qho ntxiv, nws tso cai rau kev npaj ntawm nitriles los ntawm oxidative kev hloov pauv ntawm cawv, aldehydes, thiab amines.
Cov tshuaj tiv thaiv nrog cov ntxhiab tsw aldoximes facilitates kev npaj ntawm hloov chaw ntawm Anilines. Nws tuaj yeem ua haujlwm hauv oxidative cyclization ntawm cov Cyclization homoalyClic los ua BetrahyDrofuran. Tsis tas li ntawd, nws plays lub luag haujlwm hauv oxidative tsis muaj cocring ntawm -hydroxykimone rau synthesis ntawm isoxazoline n-oxides. Nyob rau hauv synthesis ntawm aminopeptidase inhibitors, nws yog koom nrog hauv lub nplhaib-nthuav kev ua. Ntxiv mus, nws koom nrog oxidation thiab kev sib txawv ntawm cov acidic tej yam kev mob.
