I have a radical reaction which I got from an organic chemistry lecture and was drawing the possible mechanism for it.
Fig 2. shows my thought process. The I is removed making a radical and ISnBu$_3$. The radical opens the ring and the new radical is formed which then reacts with the hydrogen radical. However Fig 1. shows the reactants and products from the lecture which don't match with what I thought.
I don't see how the carbon on the "top" of the propane ring becomes part of the chain.
