- Alkoxybromination of olefins using ammonium bromide and oxone
-
A mild, efficient, and highly regio- and stereoselective method for the methoxy and ethoxy bromination of olefins has been developed using NH 4Br as a bromine source and Oxone as an oxidant. Various kinds of olefins (aromatic, linear, and cyclic olefins) afforded the corresponding alkoxy brominated products in moderate to excellent yields. Taylor & Francis Group, LLC.

- Theoretical and infrared studies on the conformational isomerism of trans-2-bromo-alkoxycyclohexanes
-
The infrared spectra of trans-2-bromo-alkoxycyclohexanes (alcoxy = OMe, OEt, OiPr and OtBu) were obtained for the neat liquid, and the C-Br stretching mode was quantitatively analyzed to give insight about the conformational isomeris

- Photo-induced Alkoxybromination of Olefins by N,N'-Dibromo-2,5-piperazinedione
-
Irradiation of N,N'-dibromo-2,5-piperazinedione in dichloromethane in the presence of an alcohol induced alkoxybromination of cyclohexene to give trans-1-bromo-2-alkoxycyclohexane in a good yield.The reaction was thought to proceed through an ionic mechanism.
