Talk:Ring expansion and contraction

List?

edit

Should this article be changed to List class? It seems that ring expansions and contractions have no unifying properties apart from the migration of an alkyl group - and so there may never be enough for a full article. Then again, they do all involve the migration of an alkyl group. All the Featured lists have nice long leads, so that isn't an issue. Tomásdearg92 (talk) 02:19, 5 May 2014 (UTC)Reply

No, not all do. The list is incomplete, and poorly explained and illustrated. We can change this. Do not change the status of the article, please. This is a fantastically rich and important area of chemistry. It is just not well developed here, in this article. Le Prof Leprof 7272 (talk) 06:20, 23 May 2014 (UTC)Reply

Moving single appearing citation that biases presentation here to Talk

…until good secondary sources and representative illustrations can be found to cover the whole of the article. This is for two reasons,

  • (i) the imbalance reflected in elaborating, illustrating, and sourcing one of the whole list of these reactions, and
  • (ii) the poor quality of the source that appears—it is a primary source, not secondary, and a poor quality primary source.

Moreover, the only reaction that is illustrated is not one of the more important reactions listed, either in terms of modern chemistry theory or applications.

Bottom line, WP does not exist to feature reactions that one finds accidentally, or one's favorite reaction, or or reactions that one has happened to publish on. (My first-rank new reaction discoveries do not appear in WP, at all; they are too specialized.) It is to provide encyclopedic content. Hence, one Molecules citation doth not an encyclopedic article make. Discover a new broadly applicable 5+3 cycloaddition reaction, see it in 4-5 publications so it is written up in an Angewandte review; then, even if yours, objectively, it might just belong in WP.

Here is the removed detail and citation, with markup ref language changed to all caps indicators of start and finish of the sub-par reference:
 
See above for reasoning. Note, as edit summary states, "Andy-Yang…" reaction is removed for non-notariety/possible vandalism. Le Prof Leprof 7272 (talk) 06:40, 23 May 2014 (UTC)Reply
