There should be an oxygen analog
[edit]There should be an oxygen analog (see mellitic anhydride, but I cannot find anything with Google or Google Scholar. Any hints? --Jorge Stolfi (talk) 14:42, 13 June 2018 (UTC)
- The oxygen analog is apparently called "oxiflower" - from what I can find, it doesn't appear to have been synthesized. A computational study ( https://pubs.acs.org/doi/full/10.1021/acsomega.1c04882 ) indicates that "oxiflower" furan ring systems would reach a ring-strain minimum at 13-14 rings, much more than the 8-9 rings for the sulflower. That study also covers "oxisulflower" (alternating furan/thiophene rings, reaching a strain minimum at 10 rings) and "selenosulflower" (reaching a strain minimum at 8 rings, like regular sulflower) ~2026-33609-93 (talk) 23:37, 11 June 2026 (UTC)
