Novel ether and thioether macrocycles from phthalaldehyde
(2015-04-08) - Journal article
By reaction of phthalaldehyde (benzene-1,2-dicarbaldehyde) with ethane-1,2-diol or 2-mercaptoethanol, macrocycles containing respectively 14- and 12-membered polyether/thioether rings were obtained in low but reproducible ...
Fluorine containing amino acids : synthesis and peptide coupling of amino acids containing the all-cis tetrafluorocyclohexyl motif
(2015-05-28) - Journal article
A synthesis of two (S)-phenylalanine derivatives is described which have the all-cis, 2,3,5,6-tetrafluorocyclohexyl motif attached to the aromatic ring at the meta and para positions; the para substituted isomer is elaborated ...
Extending the family of V4+ S = ½ kagome antiferromagnets
(2015) - Journal article
The ionothermal synthesis, structure, and magnetic susceptibility of a novel inorganic–organic hybrid material, imidazolium vanadium(III,IV) oxyfluoride [C3H5N2][V9O6F24(H2O)2] (ImVOF) are presented. The structure consists ...
The X-ray Structures of 2,4-Dibromothiazole and 2,4-diacetyl-5-bromothiazole
(2015-12) - Journal article
2,4-Dibromothiazole [orthorhombic, a = 6.700(10), b = 16.21(3), c = 5.516(8) Å, space group Fmm2] shows a disordered crystal structure with molecules randomly oriented with respect to the direction of the Br–C(2)–N–C(2)–Br ...
Synthesis and characterization of green-to-yellow emissive Ir(III) complexes of pyridylbenzothiadiazine ligand
(2016) - Journal article
Reaction of Tetrakis(2-phenylpyridinato-C2,N')(μ-dichloro)di-iridium with 3-(pyridin-2-yl)-4H-benzo[e][1,2,4]thiadiazine ( L1 ) under neutral and basic media afforded the charged and neutral Ir-complexes, 1 and 2 , ...
Diphosphane 2,2′-binaphtho[1,8-de][1,3,2]dithiaphosphinine and the easy formation of a stable phosphorus radical cation
(2016-04-21) - Journal article
A convenient synthesis route to 2,2’-binaphtho[1,8-de][1,3,2]di-thiaphosphinine (3) was found. Its stable radical cation 3•+ was accessed easily through one-electron oxidation with NOBF4.
Synthesis and crystallographic characterisation of Mg(H2dhtp)(H2O)5·H2O
(2016-03) - Journal article
A mononuclear complex of composition Mg(H2dhtp)(H2O)5·H2O has been prepared and characterised crystallographically.
Pyridine-promoted dediazoniation of aryldiazonium tetrafluoroborates : application to the synthesis of SF5-substituted phenylboronic esters and iodobenzenes
(2015-08-26) - Journal article
Pyridine promotes dediazoniation of aryldiazonium tetrafluoroborates. The formed aryl radicals were trapped with B2pin2, iodine, or tetrahydrofuran to afford boronic esters, iodobenzenes and benzenes, respectively. The ...
Selectively fluorinated cyclohexane building blocks : derivatives of carbonylated all-cis-3-phenyl-1,2,4,5-tetrafluorocyclohexane
(2015-12-21) - Journal article
Palladium catalysed carbonylation reactions using the meta- and para-iodo derivatives of all-cis-3-phenyl-1,2,4,5-tetrafluorocyclohexane ( 4 ) are illustrated as the start point for a variety of functional group interconversions. ...
