Initial comments:
The article is reasonably laid out, but needs significantly more details.
Suggestions:
- Specific examples and details regarding the "numerous additional calculations and experiments" for the mechanism would be nice. Also, can we see some details about the bullet pointed pieces of evidence? More carbonyl groups slowing the reaction down doesn't seem to scream "concerted mechanism" to me. The solvent effect and stereospecificity are much more convincing, but could use reaction schemes. What do isotope effects say?
- Can we please replace the phrase "high negative entropic energy and moderate enthalpy requirements" with some experimental numbers and words like "highly negative entropy of activation" instead?
- What do you mean by "maximum gains in sigma bond energy"? Can you make some general comments on where the delta G in the reaction comes from?
- This could use significantly more examples and applications in synthesis. Are there catalytic variants? — Preceding unsigned comment added by E kwan (talk • contribs) 19:59, 24 October 2011 (UTC)
