The arrows on structures 2b and 2c are incorrect. as they are drawn, they show the formation of a 5 membered ring (which doesn't occur(they're resonace structures)) 2b and 2c need 2 arrows going back the other way. —Preceding unsigned comment added by 132.234.251.211 ( talk) 01:23, 25 February 2008 (UTC)
No I agree, the arrows should be from the internal olefin to the cation and from the exo-methylene to the internal position, i.e. 2 arrows where there is one; as drawn the arrows do mean nothing in conjunction with the structures (even as resonance arrows). —Preceding unsigned comment added by Etheiste ( talk • contribs) 01:08, 28 May 2009 (UTC)
I've expanded this article significantly, and in the interest of full disclosure, I should mention that I work for Professor Frontier, mentioned in the article several times, and whose review was my primary resource for the expansion. I tried to incorporate research with a neutral point of view with research from the "big names" (Tius, West, Frontier, Denmark) in Nazarov cyclization incorporated approximately equally. If anyone feels as though I've leaned too far towards Frontier's chemistry, please feel free to change or remove any sections, or add to this discussion. M.Levin 04:59, 24 January 2011 (UTC)

EDIT: I've changed all the figures to thumb-type images so that the captions are visible without hovering over. Hopefully this is in line with what you wanted? M.Levin 18:19, 11 March 2011 (UTC)
