8-Quinolyl phosphate (8QP) in the presence of the trivalent lanthanide ions (Ln = La, Sm, Eu, Tb, and Er) forms a [Ln ? 8QP]+ complex where the lanthanide ion catalyzes hydrolysis of 8QP. In reactions with Tb 3+ or Er3+, t
(AEDPH3)·(8-OQH)·(H2O): A yellow supramolecular plaster with ammonia adsorption and ammonia-induced discoloration properties

, p. 2732 - 2737 (2014)
A novel supramolecular plaster, namely (AEDPH3)·(8-OQH) ·(H2O) (1), is synthesized and characterized. This plaster is an organic acid-base compound, which shows a three-dimensional (3D) sandwich-type supramolecular network. It is a yellow gelling material with excellent mechanical properties superior to that of gypsum plaster. Moreover, the plaster can adsorb ammonia (NH3) effectively, and exhibits an interesting ammonia-induced discoloration property.
Photodegradation of quinoline in water
Kochany, Jan,Maguire, R. James
, p. 1097 - 1110 (1994)
The photodegradation kinetics of quinoline have been studied at 313 nm and in sunlight in organic-free water, lake water, and water containing several different solutes. The half-life of sunlight photodegradation is slightly shorter in lake water than in organic-free water (4-8%, depending upon the season). In near-surface lake water at 40° N latitude in summer, quinoline was predicted to degrade readily in sunlight, with a half-life of about 14 calendar days. The calculated half-life in winter was about 123 calendar days. The photodegradation of quinoline was accelerated significantly by NaNO3 and dissolved organic matter, two effective producers of hydroxyl radicals in aquatic environments. The rate was also faster at pH 4.5 than at pH 7.0. Two photoproducts were identified in low yield, 2-hydroxyquinoline and 8-hydroxyquinoline; prolonged irradiation appeared to destroy the aromatic nucleus.
Effect of Poly(diallyldimethylammonium Chloride) and of Poly(ethyleneimine) on the Esterolysis of 8-Acetoxyquinoline
Arcelli, Antonio,Concilio, Carlo
, p. 1327 - 1331 (1983)
The esterolysis of 8-acetoquinoline (8-AQ) in aqueous solution in the presence of an excess of poly(diallyldimethylammonium chloride) (PDDA) or poly(ethylenimine) (PEI) was investigated at 30 deg C.In the presence of PDDA hydrolysis takes place and the polyion does not affect the rate of the reaction.In the presence of PEI the ester undergoes aminolysis and saturation kinetics are observed.The pH dependence of kobs, the apparent first-order rate constant of esterolysis, can be explained on the basis of the pH dependence of pKapp and the degree of ionization of PEI.A Broensted relationship has already been found for the aminolysis of 8-AQ with primary and secondary amines of low molecular weight.By extending the relationship to the reaction between the polymeric amino groups in PEI and 8-AQ, we can quantitatively predict the pH dependence of kobs under saturation conditions, provided that the proper values of pKapp of the amino groups are considered.

Quinoline and its derivatives were synthesized by cyclocondensation of anilines with propane-1,3-diol in 57-96% yield in the presence of iron-containing catalysts in carbon tetrachloride.
Solid-state structural transformations of two AgI supramolecular polymorphs to another polymer upon absorption of HNO3 vapors
Akhbari, Kamran,Morsali, Ali
, p. 2787 - 2789 (2013)
Solid-state structural transformation of two polymorphic forms of [Ag(8-HqH)(8-Hq)]n (1α and 1β, where 8-HqH = 8-hydroxyquinoline and 8-Hq- = 8-hydroxyquinolate) to {[Ag(8-HqH)2]NO3}n (2) has been observed upon solid-gas reaction of compounds 1α and 1β with HNO3 vapors. Solid-gas reaction of compound 2 with hydrated vapors of NH3 results in the formation of only the 1β polymorph, while solid-solid reaction of compound 2 with KOH results in the formation of a 1α and 1β mixture with chiral and achiral space groups of P212 121 and Pbcn, respectively.

Photocatalytic synthesis of phenols mediated by visible light using KI as catalyst
Huiqin, Wei,Wu, Mei
supporting information, (2021/11/30)
A transition-metal-free hydroxylation of iodoarenes to afford substituted phenols is described. The reaction is promoted by KI under white LED light irradiation and uses atmospheric oxygen as oxidant. By the use of triethylamine as base and solvent, the corresponding phenols are obtained in moderate to good yields. Mechanistic studies suggest that KI and catalysis synergistically promote the cleavage of C-I bond to form free aryl radicals.
