Wittig reagent yog siv los npaj cov alkenes thiab ua kom cov pa roj carbon ntau ntawm cov saw hlau tsis zoo. Lub precursor ntawm Wittig cov tshuaj tiv thaiv yog dav siv nyob rau hauv synthesis ntawm unsaturated bonds nyob rau hauv cov ntaub ntawv siv lead ua kua. Nws kuj yog siv dav hauv cov organic synthesis. Nws yog ib qho zoo cationic theem hloov pauv catalyst.
