CSMCRI/CSIR 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
- Brominating reagent for substitution (BR-S);
- Brominating reagent for addition Reactions (BR-A); and
- Brominating reagent for oxidations (BR-O). The reagent can be prepared cost-effectively from the intermediate of bromine recovery plants.
Replacement of the corrosive elemental bromine;
Safe, easy to handle & transport;
Avoids the need of special equipments;
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 byproducts;
Kg scale preparation
Bromo-compounds manufacturers
The process does not generate hazardous by-products.
Bromine intermediate, chlorine and alkali
As desired by the customer for the their production.
The technology is feasible for the large-scale production of green brominating reagents from the intermediate of bromine manufacturing process. The reagent is equivalent (alternate) to liquid bromine in many transformations
The brominating reagent cost will be approximately equivalent liquid bromine + 20%.
Preparation of non-hazardous brominating reagents ; Pilot scale demonstration
