Examples
-
For my graduate work, I initially chose a project related to the Pettit work and finished studying the anti-aromaticity of cyclobutadiene.
-
Now, aromaticity is a fuzzy concept, and there is no general agreement on what it is.
-
Sure, bonding is more difficult, and let's not start about aromaticity.
-
NMR shifts will give us experimental backup on our notion of aromaticity, and so do bond lengths.
-
Based on the new atom type list, I have rewritten the Hückel aromaticity detector and it applies these rules:
-
There are many other details to aromaticity than I just covered.
-
I asked Peter about this, and whether OpenNMR predicted shifts could indeed confirm aromaticity of compounds, and he replied and showed that the predicted spectra could be used to distinguish between C-C and C=C bonds.
-
Aromaticity beyond that is even less well defined than aromaticity in general.
-
I commented the following which was in moderation at the time of writing, and that gets us to experimental evidence for aromaticity:Thanx for the elaborate answer.
-
Very often this is seen as indicating aromaticity.
