Abstract 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
