Sodium periodate, dawb crystalline hmoov, soluble nyob rau hauv dej, acetic acid, hydrochloric acid, sulfuric acid, nitric acid, insoluble nyob rau hauv ethanol. Sodium periodate yog ib qho dawb quadrangular siv lead ua uas tuaj yeem yaj hauv dej thiab kua qaub. Nws muaj cov kab tsis huv xws li cov kua qaub dawb, chloride, bromide, sulfate thiab cov hlau hnyav. Nws tuaj yeem ua kom zoo los ntawm recrystallization los ntawm cov kua dej. Cov khoom no muaj zog oxidation kev ua tau zoo. Txawm hais tias nws tsis hlawv nws tus kheej, nyob rau hauv qee qhov xwm txheej, cov khoom uas raug kev sib txhuam, kev co thiab kev cuam tshuam, kub kub lossis kua qaub thiab alkali tuaj yeem decompose, hlawv thiab tawg thaum lawv raug dej noo, organic tshuaj, txo cov neeg ua haujlwm thiab cov khoom siv. incompatible nrog xwm. Sodium periodate muaj ob lub ntsiab siv hauv cov organic synthesis: ua oxidant thiab catalyst. Vim yog solubility, oxidation cov tshuaj tiv thaiv ntawm sodium periodate feem ntau yog nqa tawm hauv dej. Vim hais tias ntau cov ntaub ntawv organic yog insoluble hauv dej, nws yog ib qho tsim nyog yuav tsum siv cosolvent. Thaum muaj ib theem hloov catalyst los yog sodium periodate yog loaded ntawm ib tug inert carrier, oxidation cov tshuaj tiv thaiv kuj yuav nqa tawm nyob rau hauv ib tug ob-theem system.
Sodium periodate muaj ob lub ntsiab siv hauv cov organic synthesis: ntawm ib sab, nws yog siv los ua oxidant; Ntawm qhov tod tes, nws yog siv los ua catalyst. Cov tshuaj tiv thaiv oxidation ntawm sodium periodate tshwm sim hauv dej, tab sis rau cov organic teeb meem, nws yog insoluble hauv dej, yog li cov cosolvent yuav tsum tau siv. Thaum muaj ib theem hloov catalyst muaj li ntawm quaternary ammonium ntsev nyob rau hauv ob-theem kev daws teeb meem, los yog muaj ib tug inert cab kuj nyob rau saum npoo ntawm oxidant, oxidation cov tshuaj tiv thaiv kuj tshwm sim.
Raws li oxidant dav dav, sodium periodate tuaj yeem oxidize cawv rau carbonyl compounds (Formula 1, Formula 2)
Sodium periodate tseem tuaj yeem siv los rhuav tshem glycol tebchaw thiab oxidize lawv rau dicarbonyl compounds (Formula 3, Formula 4)
Sodium periodate txawm lov C=C ob daim ntawv cog lus thiab oxidizes rau carbonyl compounds. Nws yog hu ua nto moo Lemieux-Johnson reagent (formula 6) thaum ua ke nrog OsO4 rau oxidize alkenes. Tsis tas li ntawd, nws cov khoom txo qis tuaj yeem rov qab siv tau los ntawm lub sijhawm oxidation.
(Formula 5)
Kev xaiv oxidation ntawm sulfide rau sulfoxide yog ib qho tseem ceeb heev cov tshuaj tiv thaiv, vim hais tias sulfoxide yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis. Nws tuaj yeem cuam tshuam nrog sodium periodate hauv cov tshuaj methanol ntawm 0 oC. Sulfide yuav raug oxidized rau sulfone ntawm qhov kub thiab txias los yog ntxiv sodium periodate ntau dhau. Thaum muaj acidic alumina los yog silica gel, sodium periodate tuaj yeem xaiv oxidize sulfide rau sulfoxide (siab yield tuaj yeem tau txais ntawm chav tsev kub) (Formula 7, Formula 8). Kev koom tes ntawm theem hloov catalyst kuj ua rau sulfide xaiv oxidized rau sulfoxide (Formula 9)
Tsis tas li ntawd, sodium periodate tuaj yeem siv los ua ib qho pheej yig catalyst rau sulfonation synthesis ntawm aryl pawg (Formula 10).
Cov tshuaj tiv thaiv mob me heev, qhov tawm los yog siab, lub sijhawm tshuaj tiv thaiv luv luv, thiab kev xaiv zoo.
