Research paper thumbnail of Functional Group Transformations of Diols, Cyclic Ethers, and Lactones Using Aqueous Hydrobromic Acid and Phase Transfer Catalyst under Microwave Irradiation

Organic Process Research & Development, 2003

Synthesis of bromoalkanols has been achieved from diols, ethers, and lactones using aq HBr (48%) ... more Synthesis of bromoalkanols has been achieved from diols, ethers, and lactones using aq HBr (48%) and tetrabutylammonium iodide/bromide as phase transfer catalyst under microwave irradiation. This environmentally benign route provides enhanced yields of products and does away with the use of benzene as compared to existing conventional methods.
