Parent phosphole first described in 1987... or 1983? edit
The article currently states that:
- "the parent phosphole itself was first described in 1987"
- Quin, L. D. (2000). A Guide to Organophosphorus Chemistry. John Wiley & Sons. ISBN 0-471-31824-8.
I tried to find the original paper to add to the list of references, but it seems that phosphole was actually first made in 1983:
- "The parent phosphole C4H4PH is observed here for the first time"
- Charrier, C.; Bonnard, H.; de Lauzon, G.; Mathey, F. (1983). J. Am. Chem. Soc. 105: 6871–6877. doi:10.1021/ja00361a022.

Phosphole was subsequently further characterised by 1H and 13C NMR spectroscopy in 1987 by the same chemists:
- Charrier, C.; Mathey, F. (1987). Tetrahedron Lett. 28: 5025–5028. doi:10.1016/S0040-4039(00)96686-3.

Does anyone know any more about the issue?
Phosphole vs. Arsole edit
In multiple Wikipedia articles mentioning these compounds phosphole is described as being non-aromatic, but its analogon arsole is described as moderately aromatic. Is this true that arsole is more stable than phosphole? I would rather expect the opposite because phosphole is "closer" to the aromatic compound pyrrole... --79.243.252.242 (talk) 16:39, 1 September 2013 (UTC)
- These articles are written by diverse editors, and for topics that involve a lot of "grayness" (and where the answer does not really make any difference) you will find inconsistent descriptions. Probably you would find the same diversity of opinion in various textbooks. --Smokefoot (talk) 16:54, 1 September 2013 (UTC)
