Mechanism

Step 6 is incorrect here: when D2O is used as solvent, the salicylaldehyde formed is completely deuterated at the aldehyde position but nowhere else. It must abstract a proton (or deuteron) from the solvent rather than taking it straight from the carbon, or maybe (possibly more likely?) it forms a double bond to the aromatic ring when it adds in.

URL: n-dash vs. hyphen

The URL of the Reimer-Tiemann reaction article makes it difficult to link to, at least for some text-encoding systems. The URL currently has an en-dash (unicode 2013) between Reimer and Tiemann

https://en.wikipedia.org/wiki/Reimer–Tiemann_reaction

Copying this URL and pasting it into a browser works fine, but pasting it into an html file and clicking on the resulting link can make the browser misread the file as

https://en.wikipedia.org/wiki/Reimer–Tiemann_reaction

and Wikipedia returns an error message for that URL (no such article). Substituting a hyphen (unicode 2010) for the en-dash in the URL

https://en.wikipedia.org/wiki/Reimer-Tiemann_reaction

gets the browser to the right article via a redirect (Redirected from Reimer-Tiemann reaction)

Can the URL be changed to include the hyphen rather than the dash? Otherwise, copying the displayed URL and pasting it into an html file can cause a broken link. (Details: I am using TextEdit on a MacBook Air running macOS Mojave 10.14.6 to make html files. Browsers that failed to handle the en-dash in the URL from the html file include Safari 14.1.1 and Chrome 91.0.4472.77) — Preceding unsigned comment added by DrPhlogiston (talkcontribs) 13:46, 4 June 2021 (UTC)

So just use the URL that links to the hyphen https://en.wikipedia.org/wiki/Reimer-Tiemann_reaction – it will automatically redirect to the actual title that uses the hard-to-type en dash. – wbm1058 (talk) 12:06, 14 June 2021 (UTC)
