Talk:Cope rearrangement

Although some stuff needs to be filled in on this article, actually it seems to be somewhat better looking than the other.

This doesn't make sense.
This statement is confusing:

"Although the Cope rearrangement is concerted and pericyclic, it can also be considered to go via a transition state that is energetically and structurally equivalent to a diradical. This is an alternative explanation which remains faithful to the uncharged nature of the cope transition state, while preserving the principles of orbital symmetry."

Does that mean that the TS has diradical character in the concerted mechanism? Or that the Cope sometimes goes through a diradical mechanism? It has to be one or the other. A TS with diradical character implies a concerted mechanism with no intermediate, whereas a diradical implies a stepwise mechanism with an intermediate.
