Abstract
- Mechanochemical milling of equimolar mixtures of salicylic acid with three hydroxy derivatives of pyridine provided three new phases. With 2-hydroxypyridine, which is in fact present as 2-pyridone, a discrete cocrystal supramolecular assembly is formed. 3-hydroxypyridine and salicylic acid formed a salt and an extended network of hydrogen bonds while the product of the reaction of 4-hydroxypyridine (present as 4- pyridone) and salicylic acid remained structurally uncharacterized. All three hydroxypyridines retain the tautomeric form as in their respective pure phases upon cocrystal formation. Where possible, reaction profiles have been extracted from in situ monitoring via Rietveld refinement to show direct product formation which could be well described using the first-order reaction rate law.
