Talk:Carbon suboxide

Untitled

At the end of the carbon suboxide article, carbon suboxided is said to be "postulated to be poly(α-pyronic)". Now, this, of course, leads to the question, what is "poly(α-pyronic)"? This is a question, however, to which I found no answer. I searched on Wikipedia for α-pyronic and pyronic, and finding nothing, I then searched on Google for α-pyronic, pyronic, and finally poly(α-pyronic). The only relevant response I got was a small paper that was about carbon suboxide, and said, without detail, that poly-carbonsuboxide should be poly(α-pyronic). So, what is "poly(α-pyronic)"?--IdiotsOpposite (talk) 03:40, 15 February 2008 (UTC)

I think Pyrone shows a image of 2-pyrone (α-pyrone) and this is the substructure present in poly-carbonsuboxide.--Stone (talk) 06:12, 15 February 2008 (UTC)

Cumulene

The page for cumulenes specifies that all cumulenes are hydrocarbons - are these oxocarbons cumulenes or not, then? PurpleQuaver (talk) 01:12, 12 July 2022 (UTC)
