'Polyacetylene' versus 'polyyne' nomenclature

Latest comment: 3 years ago1 comment1 person in discussion

It seems like most early works use 'polyacetylenes' to refer to these compounds. Can anyone clarify when/why the switch happened to the 'polyyne' nomenclature? I understand ghtat there is a conflict with the acetylene polymers now known as polyacetylenes, but it seems like polyynes were called polyacetylenes first?

Misidentified plant

Paramacrolobium ceruleum is a legume from the Fabaceae family, not the Loranthaceae family. --Jorge Stolfi (talk) 20:19, 28 June 2009 (UTC)Reply

I agree. What's not clear to me (I'm a botanist, not a chemist) is whether the compound occurs in both Paramacrolobium AND a plant in the Loranthaceae family, so I'm not sure how to edit this. If no one weighs in soon, I guess I'll do my best. Spoonlegs (talk) 15:48, 23 November 2017 (UTC)Reply

Pronunciation?

How is this word pronounced? Some IPA would be nice. --RokerHRO (talk) 10:37, 8 November 2010 (UTC)Reply

I have so tagged it, along with ""oligoynes", for the attention of an IPA expert. Reify-tech (talk) 17:42, 17 July 2015 (UTC)Reply

The key scientific component of these name is the -yne, which is /ˈaɪn/. "Poly" is /ˈpɒlɪ/. "Oligo" is um.../əˈlɪɡə/ according to oligomer, but I've often heard at least the second "o" and sometimes also the first as a /oʊ/. DMacks (talk) 19:41, 17 July 2015 (UTC)Reply

Ambiguous referent. What is "they"?

Latest comment: 2 years ago1 comment1 person in discussion

This occurs in a sentence roughly half way through the first paragraph.

"They are also sometimes referred to as oligoynes . . ."

It is unclear to me what "they" refers to.

Would it be correct to rephrase it thusly?

"Polyynes are also sometimes referred to as oligoynes . . ."
