Polymorphism, weak interactions and phase transitions in chalcogen-phosphorus heterocycles
(2018-06-28) - Journal article
A series of novel P-E containing heterocycles with aromatic backbones were synthesised and characterized by single crystal and powder X-ray diffraction, microanalysis and mass spectrometry. 31P and 77Se solution- and ...
Synthesis of the natural product descurainolide and cyclic peptides from lignin-derived aromatics
(2018-01-14) - Journal article
Alternative sources of potential feedstock chemicals are of increasing importance as the availability of oil decreases. The biopolymer lignin is viewed as a source of useful mono-aromatic compounds as exemplified by the ...
Unprecedented strongly panchromic absorption from proton switchable iridium(III) azoimidazolate complexes
(2015-12) - Journal article
Two novel heteroleptic iridium(III) complexes bearing an aryldiazoimidazole ligand are reported. These complexes differ structurally with respect to the protonation state of the imidazole ring, but can be independently ...
6-exo-trig Michael addition-lactonizations for catalytic enantioselective chromenone synthesis
(2017-02-28) - Journal article
The catalytic enantioselective 6-exo-trig Michael addition-lactonization of enone-acid substrates to form cis-chromenones with high diastereo- and enantiocontrol was developed using the commercially available isothiourea ...
Cationic platinum(II) complexes bearing Aryl-BIAN ligands : synthesis, structural and optoelectronic characterization
(2015-01-12) - Journal article
Five cationic platinum(II) complexes bearing a 2-(3’-substituted-aryl)pyridine cyclometalating ligand (C^N) and a neutral Ar-BIAN ligand have been synthesized: [Pt(ppy)(PhBIAN)]PF6, 1, [Pt(3Fppy)(PhBIAN)]PF6, 2, ...
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 ...
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.
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. ...
