Alkene geometry edit
The reaction as drawn appears to be balls. The hydrogens must be coplanar and the double bond shown is definitely cis. Any other thoughts? OcelotIIX (talk) 21:17, 18 January 2009 (UTC) My bad, wasn't thinking carefully enough. OcelotIIX (talk) 21:19, 18 January 2009 (UTC)
- Changed it to right structure (same as in literature) Chemiker88 (talk) 21:34, 23 July 2013 (UTC)
- Looks good! The alkene really is a bit twisted (there are actually two enantiomers, represented in the paper using wedge/dot bonds for the H off the alkene) but it really does need to start out looking trans. DMacks (talk) 21:46, 23 July 2013 (UTC)
- Yeah i know that. In this case i looked it up and in doi:10.1021/ja8001919 it's just like i draw it (wdge/dot bonds are only drawn if it's a trans-cycloocetnol), there are also other possibilities to draw this, but in this case i trust in Prof. Fox, as he is an expert in this.

Physical properties edit
The physical properties of cis vs trans isomers need clarification. The figures in the chem box are for cis. — Preceding unsigned comment added by 175.38.163.188 (talk) 19:29, 23 August 2013 (UTC)
