1. The problem statement, all variables and given/known data Propose the mechanism through which dimethyl maleate convert to dimethyl fumarate. 3. The attempt at a solution I think free radical bromination reaction plays a role here, but I'm not sure how. We first get two bromine radicals, one of which attacks the double bond in dimethyl maleate. What forms next? Does bromine ever get attached to the DMM? Thank you so much for your help!
