Title: Writing convention for deuterated solvents
Post by: JuliaLouttit on May 18, 2018, 07:07:09 AM

Hi all,

I've stumbled on a problem: I'd like to confirm that deuterated solvents should be written with subscript numbers and italicized Ds, when this follows the solvent name (e.g methanol-d₄), but while trying to find a definitive authority on this, I come up blank. I can't find recommendations in IUPAC books etc. Can anyone offer assistance here, even to point to an authoritative source on writing conventions? Thank you in advance!  :)

Although I can be wrong, that particular nomenclature may be archaic, or an older convention, or a localized thing because the printer couldn't handle it any other way.

I have not scoured this particular reference thoroughly, but it seems to me, that IUPAC nomenclature requires identifying the atom, even for deuterium.

I've seen it this way, as well as with the d4 label at the start.

Having said that, Fulmer et al, Organometallics, 2010, 29, 2176-9 (doi: 10.1021/om100106e) uses your convention.

I would follow JACS usage, which presumably is strictly IUPAC.

Regards.

Quick Google search reveals,

https://pubchem.ncbi.nlm.nih.gov/compound/Methanol-d4

Perdeuteromethanol (Methanol-d4) gives trideuterio(deuteriooxy)methane as IUPAC name.
