Talk:Ene reaction

Comments
Impressions: The article has an appropriate number of examples and is well organized. However, the presentation could use some work.

Suggestions:

- Please render all figures using standard ACS settings in ChemDraw. I am not sure about the copyright implications of copying and pasting as you've done.

- You have no lead section. That's one paragraph outlining the article, along with some representative scheme.

- Surely there is a better structure than HF/3-21g to show for the mechanism?

- Figure 4 refers to "anti" and "syn," but it is not clear what those are referring to.

- The substantially higher barriers of the ene reaction over the Diels-Alder reaction are worth commenting on. This provides a rationale for the kinds of strongly Lewis acidic catalysis one sees in the literature.

- Figure 6 seems to be suggesting a steric origin for the endo effect in these reactions. Can you expand on this with some examples? How large is endo/exo selectivity in these reactions? Is it really thought to be purely steric in origin?

- Figure 13 seems to be very small. — Preceding unsigned comment added by E kwan (talk • contribs) 22:24, 24 October 2011 (UTC)
 * Cut'n'paste from copyrighted sources is not permitted except under the limited WP:Fair use cases. At least some of these images appear to include some creative work (choice of perspective for 3D illustrations and arrangement for tables and such)--even including figure-numbers specific to presumably their source-article and confusing to WP use. And they are certainly not "own work" if they are scans of someone else's work even if that work were free. DMacks (talk) 19:43, 5 November 2011 (UTC)

- I think there is a mistake in the last figure (figure 19). I highly doubt the yield is only 2%.88.64.30.99 (talk) 12:37, 4 January 2012 (UTC)
