Abstract:
Although 2-hydroxypyridine is one thousand times less acidic than its isomer 3-hydroxypyridine and ten million times less acidic than acetic acid, in the aqueous hydration of 1 mol/L acetone at 298 K the catalytic effect of added 2-hydroxypyridine is 600 000 times greater than that of 3-hydroxypyridine and 20 times greater than that of acetic acid. This experimental result is successfully reproduced by a theoretical treatment that assumes that solvent molecules participate in a cyclic cooperative mechanism that avoids the formation of charged intermediates. However, the theoretical treatment d

Phenols are well-known precursors of cyclohexadienones, which have widespread applications in organic synthesis. In contrast, their hydroxypyridine counterparts have not been explored yet. An unprecedented oxidative dearomatization of a 3-hydroxypyridine involving an unexpected deformylation step is reported. The chemical reactivity of the resulting unreported azacyclohexadiene-type compound was also explored.

The molecules form a two-dimensional hydrogen-bonded network resulting in sheets of hydrogen-bonded molecules that lie parallel to the (10\overline 2) plane. In contrast, 3-hydroxypyridine and terephthalic acid form the salt bis(3-hydroxypyridinium) terephthalate, 2C5H6NO+·C8H4O42−, giving rise to two-dimensional hydrogen-bonded sheets extending through the lattice parallel to the (10\overline 2) plane.

Abstract:
Six reaction products of ZnII and NiII with pyridine-2,6-dicarboxylic acid (H2Lig1), 4-chloropyridine-2,6-dicarboxylic acid (H2Lig2) and 4-hydroxypyridine-2,6-dicarboxylic acid (H2Lig3) are used to pinpoint the structural consequences of crystal field stabilization by an incomplete d shell. The pseudo-octahedral ZnII coordination sphere in bis(6-carboxypicolinato)zinc(II) trihydrate, [Zn(C7H4NO4)2]·3H2O or [Zn(HLig1)2]·3H2O, (1), is significantly less regular than that about NiII in the isostructural compound bis(6-carboxypicolinato)nickel(II) trihydrate, [Ni(C7H4NO4)2]·3H2O or [Ni(HLig1)2]·3H
