Flash vacuum pyrolysis of α-acyl-o-methoxybenzylidenetriphenylphosphoranes to give 2-substituted benzofurans
(ARKAT, 2000) - Journal article,
The title stabilised ylides, readily prepared in one step from acid chlorides, are converted upon FVP at 850 °C into 2-substituted benzofurans. When the acyl group is aromatic it appears unchanged as the 2- substituent in ...
Adsorption energies of benzene on close packed transition metal surfaces using the random phase approximation
(2017-11-22) - Journal article,
The adsorption energy of benzene on various metal substrates is predicted using the random phase approximation (RPA) for the correlation energy. Agreement with available experimental data is systematically better than 10% ...
The X-ray structure of 4-aminobenzyl alcohol (4-aminophenylmethanol)
(2018-11-02) - Journal article,
A second polymorph of 4-aminobenzyl alcohol [orthorhombic, a = 8.95051(15), b = 5.8248(1), c = 12.1645(2) Å, space group Pna21] shows a "herringbone" structure with stacks of hydrogen-bonded molecules when viewed down the b-axis.
Quantum critical points in ferroelectric relaxors : stuffed tungsten bronze K3Li2Ta5O15 and lead pyrochlore (Pb2Nb2O7)
(2018-08) - Journal article,
We have synthesized ceramic specimens of the tetragonal tungsten bronze K3Li2Ta5O15 (KLT) and characterized its phase transition via X-ray diffraction, dielectric permittivity, resonant ultrasonic spectroscopy, and heat ...
Yeast three-hybrid screen identifies TgBRADIN/GRA24 as a negative regulator of Toxoplasma gondii bradyzoite differentiation
(2015-03-19) - Journal article,
Differentiation of the protozoan parasite Toxoplasma gondii into its latent bradyzoite stage is a key event in the parasite’s life cycle. Compound 2 is an imidazopyridine that was previously shown to inhibit the parasite ...
All-cis 1,2,3,4,5,6-hexafluorocyclohexane is a facially polarised cyclohexane
(2015-04) - Journal article,
The highest-energy stereoisomer of 1,2,3,4,5,6-hexafluorocyclohexane, in which all of the fluorines are ‘up’, is prepared in a 12-step protocol. The molecule adopts a classic chair conformation with alternate C–F bonds ...
Mechanistic study of Ru-NHC-catalyzed hydrodefluorination of fluoropyridines : the influence of the NHC on the regioselectivity of C–F activation and chemoselectivity of C–F versus C–H bond cleavage
(2015-02-06) - Journal article,
We describe a combined experimental and computational study into the scope, regioselectivity, and mechanism of the catalytic hydrodefluorination (HDF) of fluoropyridines, C5F5?xHxN (x = 0?2), at two Ru(NHC)(PPh3)2(CO)H2 ...
Fractionation and DOSY NMR as analytical tools : from model polymers to a technical lignin
(2017-11-30) - Journal article,
One key challenge hindering the valorization of lignin is its structural complexity. Artificial lignin-like materials provide a stepping stone between the simplicity of model compounds and the complexity of lignin. Here, ...
Correlation of dielectric, electrical and magnetic properties near the magnetic phase transition temperature of cobalt zinc ferrite
(2017-01-07) - Journal article,
Multiferroic composite structures, i.e., composites of magnetostrictive and piezoelectric materials can be envisioned towards the goal of achieving strong room-temperature ME coupling for real practical device applications. ...
A biocatalytic approach towards the stereoselective synthesis of protected inositols
(2017-02-01) - Journal article,
A biocatalytic flow system utilising Trypanosoma brucei L-myo-inositol 1-phosphate synthase has been developed to prepare significant quantities of L-myo-inositol 1-phosphate. Using this highly valuable biochemical, we ...
