The last two posts have played a game of find the electrons. We saw how the dyotropic rearrangement of ethane borrowed electrons from the C-C bond, and how 1,2,dibromoethane went ionic on us. How about this mixed system, in which a hydrogen and a BH2 swap their positions?

Buses (and dyotropic rearrangements) always come in threes.
Sunday, June 12th, 2011More is more: the dyotropic rearrangement of 1,2-dibromoethane.
Sunday, June 12th, 2011In the previous post, I discussed what we could learn from ethane by forcing it into a pericyclic dyotropic rearrangement. We saw how it voraciously scavenged two electrons from the C-C bond to achieve this. What if we give it more electrons? Thus 1,2-dibromoethane undergoing the same reaction.
