On the bromination of aromatics, alkenes and alkynes using alkylammonium bromide: Towards the mimic of bromoperoxidases reactivity

Ultrasound-Assisted Bromination of Aromatic Rings Using NaBr/H2 O2 System

“…One example in the literature involves the use of ultrasound in an oxidative halogenation where a molybdate catalyst, with KBr and H 2 O 2 , is required, displaying reactions time as long as 2 to 4 hours. Others metal catalysed aromatic halogenation can be found in the literature …”

Eco-friendly and fast bromination of industrially-important aromatic compounds in water using recyclable AlBr3-Br2 system

“…for C 7 H 3 Br 2 NO: 276.92, found 277. So far, in view of www.bosaljournals/chemint/ editorci@bosaljournals.com good yield, the method under study could possibly be used for bromination purpose, which is efficient, eco-friendly and fast methods versus chemical methods (Aborways and Moran, 2016;Huybrechts et al, 2016;Ishii et al, 2016;Mendoza et al, 2016;Pomarico et al, 2016;Primerano et al, 2016).…”

3d Transition Metals for C–H Activation

“…Subsequent improvement in this process was achieved by Hirao and co-workers. , Here, the authors performed C–H bromination of variety of electron-rich arenes using catalytic amounts of a vanadium complex, along with Brønsted acid or Lewis acid as the additives (Scheme ). Recently, Ruíz-Guerrero and co-workers also reported a similar catalytic system for the C–H bromination of electron-rich arenes using tetrabutylammonium bromide (TBAB) as the bromine source . Under this procedure, phenol ( 94a ) and aniline ( 137a ) were selectively brominated at the para position with in a short reaction time with excellent product yields (Scheme ).…”
