Lin, Shizhuo published the artcileLayered Double Hydroxides as Reusable Catalysts for Cyclocondensation of Amidines and Aminoalcohols: Access to Multi-functionalized Oxazolines, Computed Properties of 134322-01-3, the publication is Journal of Organic Chemistry (2022), 87(2), 1366-1376, database is CAplus and MEDLINE.

An efficient catalytic protocol based on reusable MgAl-layered double hydroxides has been developed for the synthesis of multi-functionalized oxazolines via the cyclocondensation of amidines and aminoalcs. The developed method has a broad substrate scope and excellent functional group tolerance and uses a reusable catalyst. The catalyst can be conveniently recycled by filtration and reused for at least five times without obvious deactivation. Addnl., the selective ortho C-H silylation of oxazolines was performed using Ru(II) as the catalyst and tri-Et silane as the silylating reagent, which proved to be a convenient and practical method for the synthesis of versatile organosilyl-functionalized oxazolines with advantageous biol. and phys. properties.

Powell, D. B. published the artcileInfrared spectra and the stabilities of chelate metal-ethylenediamine complexes, Formula: C5H5ClIN, the publication is Journal of the Chemical Society (1961), 1112-14, database is CAplus.

cf. CA 54, 18078i. The suggestion that type A spectra are confined to complexes in which the ethylenediamine adapts the gauche configuration, while in the type B spectra the ligand has the cis configuration, has been abandoned because of x-ray studies. The spectra of PtCl₄^— salts of the ethylenediamine complex cations of Pt(II), Rh(III), Co(III), Pd(II), Cr(III), Hg(II), Cu(II), Ni(II), Co(II), Zn(II), and Cd(II) were studied. Frequencies of 2 bands assigned to N-H rocking and a band assigned to metal-N stretching decreased in the same order as the decrease in log K_av. The N-H rocking bands occur, 800-600 cm.^-1, while the metal-N stretching bands are at 585-478 cm.^-1.

New functionalized maleimides [3-(methylthio)-2,5-dioxo-1H-pyrroles] were obtained by the reaction of ketene dithioacetals with nitromethane or the reaction of nitro ketene dithioacetal with active methylene compounds in the presence of the appropriate base in DMSO followed by treatment with methanol. These maleimides reacted with various nucleophilic reagents such as electron-rich aromatic and heteroaromatic compounds like dialkylanilines, aminophenols, indoles, indolizines, and cyclazines to give the corresponding 3-aryl- or -heteroaryl-1H-pyrrole-2,5-diones. Styryl and merocyanine dyes, and polycyclic pyridazinediones as chemiluminophors and succinimides were also obtained from these maleimides with good results.

Several new delocalized cationic azo dyes incorporating a bathochromic thiazole moiety have been prepared in moderate to good yields. The synthesis involved the Knoevenagel condensation of an intermediate azo compound, bearing a terminal formyl group, with methylenic bases generated in situ from benzazolium and quinolinium salts. All dyes display strong absorption around 700 nm and have shown neg. solvatochromic behavior. The possible application of the dyes as sensitizers for photodynamic therapy was briefly discussed.

Bousrez, Guillaume published the artcileReady Access to Anhydrous Anionic Lanthanide Acetates by Using Imidazolium Acetate Ionic Liquids as the Reaction Medium, COA of Formula: C6H13I, the publication is Chemistry – A European Journal (2021), 27(52), 13181-13189, database is CAplus and MEDLINE.

Access to lanthanide acetate coordination compounds is challenged by the tendency of lanthanides to coordinate water and the plethora of acetate coordination modes. A straightforward, reproducible synthetic procedure by treating lanthanide chloride hydrates with defined ratios of the ionic liquid (IL) 1-ethyl-3-methylimidazolium acetate ([C₂mim][OAc]) has been developed. This reaction pathway leads to two isostructural crystalline anhydrous coordination complexes, the polymeric [C₂mim]_n[{Ln₂(OAc)₇}_n] and the dimeric [C₂mim]₂[Ln₂(OAc)₈], based on the ion size and the ratio of IL used. A reaction with an IL : Ln-salt ratio of 5 : 1, where Ln = Nd, Sm, and Gd, led exclusively to the polymer, while for the heaviest lanthanides (Dy-Lu) the dimer was observed Reaction with Eu and Tb resulted in a mixture of both polymeric and dimeric forms. When the amount of IL and/or the size of the cation was increased, the reaction led to only the dimeric compound for all the lanthanide series. Crystallog. analyses of the resulting salts revealed three different types of metal-acetate coordination modes where η²μκ² is the most represented in both structure types.

The cyclodehydration of (2-carboxyphenylamino)benzoic acids I (R = NO₂, CO₂H, Cl, Br, etc.) by H₂SO₄, POCl₃, or by Et polyphosphate to give mixtures of dihydroacridinecarboxylic acids II and III depended on the electronic and steric effects of R. Judicious choice of substituent and cyclizing reagent gave a large excess of 1 isomer.
