Synthesis of 1,2-dibromoalkanes

Recent Literature

In bromination of alkenes by dibromine and dealkylation of aromatic ethers by boron tribromide, a fluorous phase acts as a liquid membrane permitting passive transport of the reagents at the bottom to the top layer involving the substrates, thereby regulating the reactions.
