Hi User:bilious, this image is a redraw from Image:Arenephotocycloadditions.png but structure C is now wrong (should be a simple diene). How can this be fixed? Thanks in advance for your reply V8rik (talk) 17:22, 19 January 2008 (UTC)
- Hi V8rik! Since the original uploader did not respond for more than 10 years, I corrected the structure. --Lpd-Lbr (talk) 13:02, 31 May 2019 (UTC)
