Dioxane dibromide mediated bromination of substituted coumarins under solvent-free conditions

Chaudhuri, Subrata Kumar,Roy, Sanchita,Bhar, Sanjay

, p. 323 - 329 (2012)

An efficient solvent-free protocol for regioselective bromination of substituted coumarins has been developed by using dioxane dibromide as the solid brominating agent. The efficacy of the solvent-free protocol has been established. The effects of the electronic nature and location of the substituents on the outcome of the reaction have been rationalized with a proposed mechanism.
