TL;DR: In this article, a novel vic-dioxime, 1,2 dihydroxyimino-1-p-tolyl-3-aza-6-morpholine heptane (LH2) was prepared by reacting anti-ptolylschloroglyoxime with 4-(3-aminopropyl)morpholine in absolute THF.
Abstract: A novel vic-dioxime, 1,2 dihydroxyimino-1-p-tolyl-3-aza-6-morpholine heptane (LH2) was prepared by reacting anti-p-tolylchloroglyoxime with 4-(3-aminopropyl)morpholine in absolute THF. Mononuclear complexes with a metal–ligand ratio of 1:2 were prepared using CoII, CuII and NiII salts. The ligand and its complexes were characterized by elemental analyses, FT-IR, u.v.–vis., 1H- and 13C-n.m.r. spectra, magnetic susceptibility measurements, thermogravimetric analyses (t.g.a.), and by cyclic voltammetry.

TL;DR: In this paper, a series of trans-[PdBr2(amine)(indy)] complexes with pendant teriary amine functionalities in the side chain of the NHC ligand has been prepared by postcoordinative modification of a single bromoalkyl-functionalized precursor complex.

TL;DR: In this paper, the reaction of five Michael-type olefins with diphenylphosphine has been carried out, and the resulting 2-diphenyl-phosphino-1-cyanocycloalkanes have been obtained by treatment of methyl-3-diphosphinopropionate with the dimethylaluminum adduct of morpholine.

TL;DR: In this paper, the reactivity of azelaic acid with carboxylic acid, alcohol, amine, and amide based co-formers was screened and five new multicomponent crystal forms of AA were obtained by liquid assisted grinding and conventional solution methods.
Abstract: The reactivity of the active pharmaceutical ingredient azelaic acid (AA) with carboxylic acid, alcohol, amine, and amide based co-formers was screened. Five new multicomponent crystal forms of AA were obtained by liquid assisted grinding and conventional solution methods. The obtained forms: (i) a co-crystal with 4,4′-bipyridine (AA:BIP, 1), (ii) an anhydrous and an hydrated molecular salt with piperazine (AA:PIP, 2 and 3), and (iii) two anhydrous molecular salts with morpholine (AA:MORPH, 4) and 1,4-diazobicyclo[2.2.2]octane (AA:DABCO, 5), were fully characterized by X-ray diffraction and solid-state (SS) NMR. In all new forms the carboxylic-carboxylic R22(8) homosynthon present in AA is broken, and NH2···OCOOH or +NH2···OCOO- hydrogen bonds (HBs) become the fundamental pillars in the new supramolecular arrangements. The X-ray structure of 4 exhibits a static disorder in the hydrogen atoms engaged in an HB between two COOH moieties of AA. Density functional theory geometry optimization of the hydrogen po...
