The Data Repurposing Challenge
PM Woodall
Mar 03, 2017
When data is collected for the first time, the data collector has in mind the data quality requirements that must be satisfied before it can be used successfully—that is, the data collector ensures “fitness for use”—the commonly...
Heteropolynuclear Pt(II)–M(I) clusters with a C∧N∧C biscyclometalated ligand
The mononuclear complex [(EtO2C-CNC)Pt(dmpyz)] (1) (dmpyz = 2,5-dimethylpyrazine) has been synthesized by reaction of [(EtO2C-CNC)Pt(dmso)] (A) with dmpyz in a 1:1 molar ratio in dichloromethane. Complex 1 is the precursor for...

Investments in newer diagnostics and antimicrobial treatments are critical to improve management of enteric fever in South Asia, say Christopher Parry and colleagues
Cooperative assembly of H-bonded rosettes inside a porphyrin nanoring.
The melamine·barbiturate H-bonded rosette motif is of comparable dimensions and symmetry to the cavity of a butadiyne-linked 6-porphyrin nanoring. Functionalisation of each of the barbiturate components and the pyrimidine...

Understanding the adsorption process in ZIF-8 using high pressure crystallography and computational modelling
Claire Hobday, Christopher H. Woodall, Matthew J. Lennox, Mungo Frost, Konstantin Kamenev, Tina Düren, Carole A Morrison, Stephen A. Moggach
Dec 01, 2018
Some porous crystalline solids change their structure upon guest inclusion. Unlocking the potential of these solids for a wide variety of applications requires full characterisation of the response to adsorption and the...

Modes of activation of organometallic iridium complexes for catalytic water and C–H oxidation
Andrew J. Ingram, Arron B. Wolk, Cornelia Flender, Jialing Zhang, Christopher J. Johnson, Ulrich Hintermair, Robert H. Crabtree, Mark A. Johnson, Richard N. Zare
Jan 06, 2014
Sodium periodate (NaIO4) is added to Cp*IrIII (Cp* = C5Me5–) or (cod)IrI (cod = cyclooctadiene) complexes, which are water and C–H oxidation catalyst precursors, and the resulting aqueous reaction is investigated from...
Beyond C2 and C3
The indole scaffold will continue to play a vital part in the future of drug discovery and agrochemical development. Because of this, the necessity for elegant techniques to enable selective C–H functionalization is vast. Early...
