Journal ArticleDOI
Aromatic propellenes. Part 3. NMR, X-ray crystallography and semi-empirical calculations on the conformational isomerism of 1,2,4,5-tetrakis (pyrazol-1′-yl)-3,6-bis(3″,5″-dimethylpyrazol-1′-yl) benzene

TL;DR: In this paper, the molecular and crystal structures of two crystalline forms of 1,2,4,5-tetrakis(pyrazol-1′-yl)-3,6-bis(3″,5″-dimethylpyrazool-1″-yl) benzene and one inclusion complex with two molecules of acetic acid were determined by x-ray analysis.
Journal ArticleDOI
Utilization of charge and mass labeling for the structural identification of heterocyclic quaternary salts by mass spectrometry
Christine Enjalbal,Pierre Sanchez,Jean Martinez,Jean-Louis Aubagnac,Dionisia Sanz,Rosa M. Claramunt,José Elguero +6 more
TL;DR: Heterocyclic compounds of general formula C++2Br− were studied by tandem mass spectrometry in this paper, where fragmentations taking place from the [CH]+ and [CBr]+ ions allowed identification of their structures.
Journal ArticleDOI
New macrocyclic compounds with naphthyridine units for molecular recognition studies of biotin and urea derivatives
TL;DR: In this paper, two macrocyclic hosts containing benzenedicarboxamide or pyridine moieties and two 1,8-naphthyridine units linked by a crown ether like chain, have been synthesized and fully characterized by multinuclear NMR spectroscopy.
Journal ArticleDOI
A multinuclear magnetic resonance study of fluoro derivatives of hydroxybenzaldehydes
TL;DR: This work has been supported by the Spanish Ministerio de Ciencia e Innovacion (CTQ2010-16122), the Ministerio of Economia y Competitividad (CTZ2012-35513-C02-02, CTQ2014-56833-R), and the Comunidad Autonoma de Madrid (S2013/MIT-2841, Fotocarbon).
Journal ArticleDOI
Photoinduced processes in macrocyclic isoalloxazine–anthracene systems
M. Ángeles Farrán,Andrea Listorti,Vittoria Roiati,Vittoria Roiati,Gianluca Accorsi,Giuseppe Gigli,Guy J. Clarkson,Rosa M. Claramunt +7 more
TL;DR: In this paper, two new macrocyclic structures containing 8-hidroxyisoalloxazine and 1,5-dihydroxyanthracene moieties linked by aliphatic chains of different lengths (n ǫ = 4 and 6) were designed and synthesized in order to study photoinduced electron transfer (PET) processes from the anthracene unit towards the iso-labeled singlet excited state induced by structural changes due to different intrachromophoric distances and orientations.
