Pyridinium Bromide Perbromide (PHBP) yog ib qho nruab nrab rau trisubstituted enones. Nws yog siv los ua ib qho yooj yim brominating reagent hauv organic synthesis. PHBP yog ib qho zoo heev brominating tus neeg saib xyuas nrog qee yam kev xaiv, cov tshuaj tiv thaiv me me, cov txiaj ntsig siab, tsis tshua muaj kev cuam tshuam, ntsuas yooj yim, thiab siv tau yooj yim. PHBP yog ib qho nyuaj ntawm bromine thiab pyridine hydrobromide, ua ib qhov chaw ntawm bromine hauv cov tshuaj tiv thaiv. Nws yog ib qho me me brominating reagent piv rau cov ntshiab bromine thiab tuaj yeem siv rau kev xaiv bromination thiab dehydrogenation cov tshuaj tiv thaiv.
