A simple and easily accessible ionic liquid, 1-butyl-3-methylimidazolium hydroxide ([bmIm]OH), has been demonstrated as an efficient promoter and reaction medium for the highly stereoselective synthesis of (Z)-vinyl bromides by the debrominative decraboxylation of dibrominated α,β-unsaturated carboxylic acids in high yields. The reaction does not require either a conventional base or an organic solvent. Copyright Taylor & Francis Group, LLC.

Vinyl bromides are versatile synthetic intermediates and widely applied in organic synthesis and pharmaceuticals. Herein, a hydrodebromination reaction of 1,1-dibromoalkenes was established via visible light catalysis. A variety of structurally different vinyl bromides were obtained in moderate to excellent yields.
Decarboxylative bromination of α,β-unsaturated carboxylic acids via an anodic oxidation

A novel bromination of α,β-unsaturated carboxylic acids was developed via a decarboxylation by virtue of a direct anodic electro-oxidation. In this method, ammonium bromide was employed as a bromine source and the reaction features transition-metal-free, short time, and no additional supporting electrolyte.

Lewis acid mediated intramolecular Nicholas reactions of aryl (Z)-enyne propargyl acetate-Co2(CO)6 complexes 1 afford benzocycloheptenyne-Co2(CO)6 complexes 2 and their heterocyclic analogues.
Facile and stereoselective synthesis of (E)-vinyl bromides by microwave-induced reaction of 1,1-dibromoalkenes using a diethyl phosphonate/EtONa/EtOH system

, p. 1491 - 1496 (2007/10/03)
(E)-Vinyl bromides were readily prepared from 1,1-dibromoalkenes by microwave irradiation within 1 min using a diethyl phosphonate/EtONa/EtOH system. This method utilizes cheap and environmentally friendly reagents, requires only a short reaction time, and gives (E)-vinyl bromides in high stereoselectivities and high yields.
