various problems

"renumbered as 2-hydroxychromen-4-one" - It's not just a renumbering; it's a tautomerization (change in the chemical structure). This needs to be explained in detail since the name and structure appear inconsistent. This also applies to entries for members of this class of compounds (i.e., brodifacoum). Drugs and poisons in this class - "The simplest synthetic molecule in the 4-hydroxycoumarin class is warfarin, in which the aromatic 3-position substituent is a simple phenyl group." Wrong! The substituent is a phenylbutanonyl and phenprocoumon is simpler. Antirodenticide? Brodifacoum is no longer used in d-CON - see cen.acs.org/articles/92/i23/Maker-Rat-Poison-d-CON.html Structures - this is unnecessarily confusing since the structures are drawn in different orientations (compare coumarin with 4-hydroxycoumarin), with bonds rotated (compare warfarin with acenocoumarol), or in different tautomeric forms (compare bromadiolone with the others). 69.72.92.1 (talk) 03:29, 16 December 2015 (UTC)[reply]

Concerning the Joseph "Staljin" section

This section has a number of problems. One is that references should use the reference tags, not in-line external links. Help can be found here: WP:REFB. Also, the standard transliteration into English is "Stalin", rather than "Staljin". The main issue, however, is the content should probably not be included. The first reference is to an NY Times book review that specifically notes that the poisoning hypothesis is a minority opinion among scholars, and therefore, far from the consensus required to present something as fact. And far too much content is included for an article on 4-hydroxycoumarins, where its potential use in a putative Stalin assassination is akin to "trivia", and doesn't call for more than a sentence, if included at all. For example, a single sentence is noted in the warfarin article under history, though I would argue that it's not significant enough to be worth mentioning at all, especially since no mention is made on either the Joseph Stalin and Death of Joseph Stalin articles. 68.48.107.79 (talk) 16:33, 30 May 2021 (UTC)[reply]

That's a banned editor who keeps pushing the idea that Stalin was poisoned, and he adds this to multiple articles. Thank you for removing it. Antandrus (talk) 19:11, 30 May 2021 (UTC)[reply]
