Usetyenziso

I-Pyridinium Bromide Perbromide (PHBP) yindawo ephakathi kwi-enones ethatyathwe endaweni yesithathu. Isetyenziswe njenge-reagent ye-brominating efanelekileyo kwi-organic synthesis. I-PHBP yi-arhente egqwesileyo ye-brominating enokukhetha okuthile, iimeko zokusabela ezithambileyo, isivuno esikhulu, ukuphendula kwicala eliphantsi, umlinganiselo olula, kunye nokulula kokusetyenziswa. I-PHBP iyinkimbinkimbi eqinile ye-bromine kunye ne-pyridine hydrobromide, esebenza njengomthombo we-bromine ekuphenduleni. Yinto ethambileyo yokucoca i-brominating xa ithelekiswa ne-bromine esulungekileyo kwaye ingasetyenziselwa ukukhetha i-bromination kunye ne-dehydrogenation reaction.
