microwave mediated debromination of vicinal Dibromides
Synthetic Communications, 2006Co-Authors: Jitender M. Khurana, Arpita AgrawalAbstract:Abstract Debromination of vicinal‐Dibromides to E‐alkenes is reported using inorganic solid supports (silica gel or acidic alumina) under microwave irradiation.

Stereoselective debromination and selective reduction of vic-Dibromides with nickel boride
Canadian Journal of Chemistry, 2006Co-Authors: Jitender M. Khurana, Bhaskar M. Kandpal, Gagan Kukreja, Purnima SharmaAbstract:A simple procedure is reported for the stereoselective debromination of vic-Dibromides with nickel boride at ambient temperature. Debromination with concomitant reduction of vic-Dibromides to give dihydro products in a one-pot reaction is also reported. α,β-Dibromoketones can also be converted to their corresponding alcohols.Key words: debromination, vic-Dibromides, stereoselective, reduction, E-alkenes.

CHEMOSELECTIVE AND STEREOSELECTIVE DEBROMINATION OF VICINAL-Dibromides WITH SODIUM DITHIONITE
Synthetic Communications, 1996Co-Authors: Jitender M. Khurana, Arti SehgalAbstract:Abstract A simple and effcient procedure for the quantitative debromination of vic-Dibromides has been reported with sodium dithionite at ambient temperature. These eliminations are chemoselective and also stereoselective.

tbaf promoted eliminationof vicinal Dibromides having an adjacent o functionalgroup syntheses of 2 bromoalk 1 enes and alkynes
Synthesis, 2011Co-Authors: Noriki Kutsumura, Keisuke Kubokawa, Takao SaitoAbstract:Syntheses of 2-bromoalk-1-enes and alkynes were achieved in goodyields by dehydrobromination of vicinal Dibromides with tetrabutylammoniumfluoride. Neighboring O-functional-group participation is importantin determining elimination reactivity.
