Cov Ntawv Thov

Pyridinium bromide perbromide (phbp) yog qhov nruab nrab rau cov oordeted enones. Nws yog siv los ua kev yooj yim brominating reagent hauv cov xwm txheej organic. PhBP yog qhov zoo tshaj plaws brominating tus neeg xaiv nrog qee yam kev xaiv, cov tshuaj tiv thaiv me me, kev ntsuas qis, ntsuas tau yooj yim, thiab kev yooj yim ntawm kev siv. Phbp yog cov khoom siv sib txawv ntawm bromine thiab pyridine hydrobromide, ua haujlwm ua ib qho chaw ntawm bromine hauv kev tawm tsam. Nws yog lub hwj chim loj tuaj yeem sib piv rau bromine ntshiab thiab tuaj yeem siv rau kev xaiv bromination thiab dehydogen cuam tshuam.
