Mechanism for oxidation of 1,10-phenathroline to 1,10-phenathroline 5,6-dione?
« on: September 17, 2016, 04:06:20 AM »
The reagents used are H2SO4, HNO3 and KBr.


I'm wondering what the exact reaction pathway is, it seems to be a mixture of bromonation and nitration but HNO3 reacts with KBr to make Br2 aswell... (I have no idea). Please help  :P

My guess: monobromination, hydrolysis to alcohol, oxidation with HNO3 to dione.
