Recoverable Bromine-Containing Nano-Catalysts in Organic Synthesis

Catalysis research under bromine is a well-known topic in organic synthesis. However, hazardous and toxic nature of bromine and its negative and deleterious effects on the human health has caused organic chemists to avoid working on bromine. Although, in the last decade, a category of heterogeneous bromine source catalysts (especially N-tribromides) has been introduced to overcome this problem, nevertheless, the recovery and reusability of these catalysts from the desired product or reaction mixture are often a laborious task. In recent times, catalysis research has clearly experienced a renaissance in the area of utility of bromine-containing nano-catalysts based on their ability to recovery and reusability; the activity of these bromine nano-catalysts was investigated in a category of organic reactions. In this review we summarized the obtained results under recoverable bromine-containing nano-catalysts with the goal of stimulating further progresses in this field.
