WebNov 9, 2024 · The latter first forms imine bonds, which then tautomerise irreversibly into the β-ketoenamine linkage. The irreversible tautomerisation results in a lower crystallinity and surface area compared to their imine counterparts. 2 The chemical stability of COFs does not only depend on the type of linking chemistry, but can also be affected by the ... WebIf an aldehyde possesses at least one hydrogen atom on the carbon atom adjacent to the carbonyl group, called the alpha (α) carbon, this hydrogen can migrate to the oxygen atom of the carbonyl group. The double bond then migrates to the α-carbon. As a result, a carbonyl compound with an α-hydrogen can exist in two isomeric forms, called …
