Web2 feb. 2015 · So clearly the H+ plays a key role. What could be going on? By analogy to the reaction of ethers with acid, the first step must be reaction of the most basic site on the molecule – the epoxideoxygen – with acid, giving us a protonated epoxide. This will function as a much better leaving groupthan does the unprotonated epoxide.
