Proposed merge with Periodinane

Not sure we need a separate page for periodinanes OrganoMetallurgy (talk) 17:50, 12 September 2017 (UTC)Reply

Oppose merge, and close—this has been open for quite long enough. Link, don't merge. The subordinate concept needs its own page. Reserve merging for two pages on the same topic. —Syrenka V (talk) 23:19, 17 March 2018 (UTC)Reply

Referring to Ref. 15

edit

"Note that in the diaryliodonium salt description, the compound is not hypervalent, and the bonding number is the standard one for iodine (λ1). It is a 8-I-2 species. In the other common description of these compounds as covalent iodanes, they are formally 10-I-3 and λ3."

i think this is not correct, as the lambda convention refers to bonding number as: "The bonding number, "n", of a skeletal atom in a parent hydride is the sum of the total number of valence bonds to adjacent skeletal atoms, if any, and the number of attached hydrogen atoms." https://iupac.qmul.ac.uk/hetero/Lm1t4.html#lm11

i.e., the formally-neutral parent hydride of a diaryliodonium salt is IH3, which is still a λ3-compound. maybe it was confused with its oxidation state (+1)? cheers 140.78.168.213 (talk) 16:39, 24 January 2024 (UTC)Reply
