Parliament and the Press : Forging the United Nations in Wartime Britain, 1939–45
2020
During the Second World War, not only the United States but also Great Britain played a leading role in planning and establishing the United Nations (UN) as a new international organisation to replace the League of Nations. While scholarship on post‐war planning is extensive, relatively little exists on how the planning process was discussed and depicted publicly in Britain. The purpose of this article is to fill such lacunae by examining the two most important domains for public discussion at the time, the press and parliament. It will argue, first, that the League of Nations’ experience – its inability to use collective force and its optimistically democratic structure – overwhelmingly sh…
Deoxygenative Divergent Synthesis : En Route to Quinic Acid Chirons
2020
The installation of vicinal mesylate and silyl ether groups in a quinic acid derivative generates a system prone for stereoselective borane-catalyzed hydrosilylation through a siloxonium intermediate. The diversification of the reaction conditions allowed the construction of different defunctionalized fragments foreseen as useful synthetic fragments. The selectivity of the hydrosilylation was rationalized on the basis of deuteration experiments and computational studies. peerReviewed

Poikatytöt, itkevät transut ja onnelliset virkanaiset : sukupuolivähemmistöjen representaatiot suomalaisissa sanomalehdissä
2015
Tämä tutkielma käsittelee sukupuolivähemmistöjen representaatiota kolmessa sanomalehdessä. Suomessa sukupuolivähemmistöjä (transihmiset ja transvestiitit) on tutkittu mediassa hyvin vähän, uutistekstissä tuskin ollenkaan. Tutkielma etsii vastausta paitsi siihen, millaisia representaatioita sukupuolivähemmistöistä käytetään, myös siihen, kenellä on oikeus sukupuolensa mukaiseen ja sukupuoltaan kunnioittavaan representaatioon. Tutkielman lähtökohtana on queer-tutkimus sisarteoria transgender studies, joka on kiinnostunut sukupuolten epätyypillisyydestä. Se painottaa sukupuolivähemmistöjen omien identiteettien, variaatioiden, säröjen ja puhetapojen kunnioittamista. Heteronormatiivisuuden ideol…

Chemoselective heterogeneous iridium catalyzed hydrogenation of cinnamalaniline
2020
International audience; Selective hydrogenation of unsaturated imines over heterogeneous catalysts is an ecologically feasible and effective way to produce commercially valuable saturated imines and unsaturated amines under mild conditions, avoiding the utilization of toxic halides. The liquid-phase hydrogenation of a model imine, cinnamalaniline, over Ir, Ru, Pd and Au catalysts was studied in polar protic (methanol, 2-propanol), polar aprotic (methyl tert-butyl ether) and non-polar aprotic (toluene) solvents at 40-80°C under atmospheric hydrogen pressure. Different metal oxides (Al 2 O 3 , ZrO 2 , SiO 2) and carbon composites based on carbon nitrides synthesized by pyrolysis of ethylenedi…
Construction of Spirooxindole Analogues Engrafted with Indole and Pyrazole Scaffolds as Acetylcholinesterase Inhibitors
2021
Twenty-five new hits of spirooxindole analogs 8a–y engrafted with indole and pyrazole scaffolds were designed and constructed via a [3+2]cycloaddition (32CA) reaction starting from three components: new chalcone-based indole and pyrazole scaffolds 5a–d, substituted isatins 6a–c, and secondary amines 7a–d. The potency of the compounds were assessed in modulating cholinesterase (AChE) activity using Ellman’s method. Compounds 8i and 8y showed the strongest acetylcholine esterase inhibition (AChEI) with IC50 values of 24.1 and 27.8 μM, respectively. Molecular docking was used to study their interaction with the active site of hAChE. peerReviewed
Straightforward One-Pot Synthesis of New 4-Phenyl-1,2,5,6-tetraazafluoranthen-3(2H)-one Derivatives: X-ray Single Crystal Structure and Hirshfeld Ana…
2022
A straightforward one-pot route for the synthesis of a new 4-phenyl-1,2,5,6-tetraazafluoranthen-3(2H)-one is reported form the direct hydrazinolysis of triketo ester and hydrazine hydrate in ethanol. 4-Phenyl-1,2,5,6-tetraazafluoranthen-3(2H)-one was subjected to aza-Michael addition and N-alkylation on reaction with a set of alkylating agents in the presence of K2CO3. Hydrazinolysis of 4-phenyl-1,2,5,6-tetraazafluoranthen-3(2H)-one ester to hydrazide and conversion of hydrazide to thiosemicarbazide were successful. X-Ray single crystals analysis and 1H, 13C NMR were used for unambiguous structure confirmation. The O…H, N…H, C…N and C…C in 2, and the N…H, …
The Difficult Marriage of Triarylcorroles with Zinc and Nickel Ions.
2022
The coordination chemistry of corrole has witnessed a great improvement in the past few years and its Periodic Table has been widened to be so large that it is compared with that of porphyrins. However, Ni and Zn ions, commonly used with porphyrins for both synthetic and theoretical purposes, are sparsely reported in the case of corroles. Here, we report synthetic protocols for preparing Ni and Zn triarylcorrole complexes. In the case of Zn, the preliminary oxidation of the free base corrole in DMSO to the neutral corrole radical is a necessary step to obtain the coordination of the metal ion, because the direct reaction led to the formation of an open-chain tetrapyrrole. The Ni complex cou…
Synthesis, X-ray Structure of Two Hexa-Coordinated Ni(II) Complexes with s-Triazine Hydrazine Schiff Base Ligand
2023
The hydrazine s-triazine ligand (E)-4,4’-(6-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)-1,3,5-triazine-2,4-diyl)dimorpholine (DMPT) was used to synthesize two new Ni(II) complexes via a self-assembly technique. The two complexes were synthesized by a one-pot synthesis strategy and characterized by elemental analysis, FTIR and single-crystal X-ray diffraction analysis to be [Ni(DMPT)(H2O)3](NO3)2.3H2O (1) and [Ni(DMPT)(H2O)3](NO3)2.H2O (2). The structures of both complexes were very similar regarding the coordination sphere and counter anions, but differ only in the number of the crystal water molecules. In the case of complex 1, there are three water molecules instead of one H2O molecu…
