Title:

Preparation of Industrially Important Organo-bromo Compounds Using Brominating Reagent
Value Proposition:

A process of preparing a green brominating reagent as a source of bromine in the bromination process.
Summary Application:

CSIR-CSMCRI has developed a green brominating reagent - a better alternative to the hazardous liquid bromine. This green brominating agent is an attractive source of bromine for bromination of various organic substrates. The reagent has been designed for three main functionalities 1) Brominating Reagent for Substitution (BR-S); 2) Brominating Reagent for Addition Reactions (BR-A); and 3) Brominating Reagent for Oxidations (BR-O). The reagent can be can be used for diverse applications.
Advantages:
  • Replacement of the corrosive elemental bromine
  • Safe, easy to handle & transport
  • Avoids the need of special equipment
  • Avoids need of catalyst
  • Maximum bromide atom efficiency
  • Operates under ambient reaction conditions
  • Easy to scale-up for the processes development
  • No formation of hazardous by-products
  • The effluent can be discharged easily without any treatment
  • Technically feasible
  • Economically competitive, readily available
