“…1449 In the synthesis of cycloheptatrienes with sulfur functional groups, Br 2 was used for oxidizing the substrate to the cyclic disulfide. 1450 Imamura et al studied the isomerization of pentane to isopentane over intermetallic compounds (LaAl 2 , CeAl 2 , PrAl 2 , ErAl 2 , SmAl, and ThAl 2 ) oxidized with Br 2 . Increasing Br 2 addition increases the activity of the catalyst, but the selectivity for isopentane decreases.…”

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.
