“…In the synthesis of 3,5-dibromo-4-oxo-2,2,6,6-tetramethylpiperidin-1-yl oxide, treatment of piperidinoxyl radical with formic acid followed by bromine afforded 75% dibromohydroxypiperidine. Oxidation of the latter with NaNO 2 afforded the desired compound . Khelevina et al studied the tetraazaporphine bromination .…”

Bromination is one of the most important transformations in organic synthesis and can be carried out using bromine and many other bromo compounds. Use of molecular bromine in organic synthesis is well-known. However, due to the hazardous nature of bromine, enormous growth has been witnessed in the past several decades for the development of solid bromine carriers. This review outlines the use of bromine and different bromo-organic compounds in organic synthesis. The applications of bromine, a total of 107 bromo-organic compounds, 11 other brominating agents, and a few natural bromine sources were incorporated. The scope of these reagents for various organic transformations such as bromination, cohalogenation, oxidation, cyclization, ring-opening reactions, substitution, rearrangement, hydrolysis, catalysis, etc. has been described briefly to highlight important aspects of the bromo-organic compounds in organic synthesis.
