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

, 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.

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.

supporting information, p. 6417 - 6421 (2021/08/03)
A thorough study of mild and environmentally friendly electrochemical-induced hydroxylation of aryl halides without a catalyst is presented. The best protocol consists of hydroxylation of different aryl iodides and aryl bromides by water solution in the presence of Et3N under air, affording the target phenols in good isolated yields. Moreover, aryl chlorides were successfully employed as substrates. This methodology also provides a direct pathway for the formation of deoxyphomalone, which displayed a significant anti-proliferation effect.
Geometric and electronic effects on the performance of a bifunctional Ru2P catalyst in the hydrogenation and acceptorless dehydrogenation of N-heteroarenes

The development of bifunctional catalysts for the efficient hydrogenation and acceptorless dehydrogenation of N-heterocycles is a challenge. In this study, Ru2P/AC effectively promoted reversible transformations between unsaturated and saturated N-heterocycles affording yields of 98% and 99%, respectively. Moreover, a remarkable enhancement in the reusability of Ru2P/AC was observed compared with other Ru-based catalysts. According to density functional theory calculations, the superior performance of Ru2P/AC was ascribed to specific synergistic factors, namely geometric and electronic effects induced by P. P greatly reduced the large Ru-Ru ensembles and finely modified the electronic structures, leading to a low reaction barrier and high desorption ability of the catalyst, further boosting the hydrogenation and acceptorless dehydrogenation processes.
Superhydrophobic nickel/carbon core-shell nanocomposites for the hydrogen transfer reactions of nitrobenzene and N-heterocycles

In this work, catalytic hydrogen transfer as an effective, green, convenient and economical strategy is for the first time used to synthesize anilines and N-heterocyclic aromatic compounds from nitrobenzene and N-heterocycles in one step. Nevertheless, how to effectively reduce the possible effects of water on the catalyst by removal of the by-product water, and to further introduce water as the solvent based on green chemistry are still challenges. Since the structures and properties of carbon nanocomposites are easily modified by controllable construction, a one step pyrolysis process is used for controllable construction of micro/nano hierarchical carbon nanocomposites with core-shell structures and magnetic separation performance. Using various characterization methods and model reactions the relationship between the structure of Ni?NCFs (nickel-nitrogen-doped carbon frameworks) and catalytic performance was investigated, and the results show that there is a positive correlation between the catalytic performance and hydrophobicity of catalysts. Besides, the possible catalytically active sites, which are formed by the interaction of pyridinic N and graphitic N in the structure of nitrogen-doped graphene with the surfaces of Ni nanoparticles, should be pivotal to achieving the relatively high catalytic performance of materials. Due to its unique structure, the obtained Ni?NCF-700 catalyst with superhydrophobicity shows extraordinary performances toward the hydrogen transfer reaction of nitrobenzene and N-heterocycles in the aqueous state; meanwhile, it was also found that Ni?NCF-700 still retained its excellent catalytic activity and structural integrity after three cycles. Compared with traditional catalytic systems, our catalytic systems offer a highly effective, green and economical alternative for nitrobenzene and N-heterocycle transformation, and may open up a new avenue for simple construction of structure and activity defined carbon nanocomposite heterogeneous catalysts with superhydrophobicity.
