Distance measurements using pulsed EPR : noncovalently bound nitroxide and trityl spin labels
(University of St Andrews, 2013-06-26) - ThesisThe function of biomacromolecules is controlled by their structure and conformational flexibility. Investigating the structure of biologically important macromolecules can, therefore, yield information that could explain ... -
Functionalised oximes : emergent precursors for carbon-, nitrogen- and oxygen-centred radicals
(2016-01-07) - Journal itemOxime derivatives are easily made, are non-hazardous and have long shelf lives. They contain weak N–O bonds that undergo homolytic scission, on appropriate thermal or photochemical stimulus, to initially release a pair of ... -
Interplay of ortho- with spiro-cyclisation during iminyl radical closures onto arenes and heteroarenes
(2013-06) - Journal articleSensitised photolyses of ethoxycarbonyl oximes of aromatic and heteroaromatic ketones yielded iminyl radicals which were characterised by EPR spectrscopy. Iminyls with suitably placed arene or heteroarene acceptors underwent ... -
Microhydration and the enhanced acidity of free radicals
(2018-02-14) - Journal articleRecent theoretical research employing a continuum solvent model predicted that radical centers would enhance the acidity (RED-shift) of certain proton-donor molecules. Microhydration studies employing a DFT method are ... -
Preparative semiconductor photoredox catalysis : an emerging theme in organic synthesis
(2015-09-09) - Journal itemHeterogeneous semiconductor photoredox catalysis (SCPC), particularly with TiO2, is evolving to provide radically new synthetic applications. In this review we describe how photoactivated SCPCs can either (i) interact with ...
