Talk:Pi-interaction

Dougherty

I have replaced references of "Daugherty" to "Dougherty" assuming that the authors intended to refer to Dennis A. Dougherty. If there's someone else named "Daugherty", please clarify. Crystal whacker (talk) 15:33, 9 December 2008 (UTC)

Merge proposal

Most recent ref (x2) is 2008, so this thing is dated. Maybe "split" would be a better proposal, or even "redistribute". Pi-interaction is a well intentioned but vague even semi-random collection of topics. This lightly edited article was created many years ago by what appears to be a homework assignment. Such assignments when unsupervised are often flops. Further comments:

• Many of the interactions in this article are not pi-interactions in the symmetry sense but interactions of various things with pi-systems.
• Some of content could be shifted to Pi-stacking and Supramolecular chemistry and charge-transfer complex (TCNE + arene)
• The organometallic subsection is too superficial and we cover that material intensely in focused articles. Organometallic chemists do not discuss the bonding as (only) "pi-interactions". Furthermore, these "interactions" are not weak, but real bonds with BDE's well above 20 kcal. I removed this part already.
• The small section "π-effects in biological systems" seems meandering essay: No pi-interactions are key to radical SAMs.
• move the anion --- arene to Cation–π interaction as counter example?

Overall, I think that someone trying to learn chemical concepts would not benefit from this article.

Unknowns:

• What to do with H₂O---arene part.
• we would convert this article into a redirect.... to what? Maybe supramolecular chemistry?
