Research overview

My main interest is in free radicals and the development of organic syntheses and novel materials based on these species. Early work was concerned with the addition of free radicals to alkenes. Currently, my research centres in (a)the development of free radical synthetic methods based on derivatives of cyclohexa-1,4-diene-3-carboxylates, on oxime oxalate amides, and on dioxime oxalates. These methods all show promise as replacements for toxic organotin hydrides. In addition my research group is developing methods for the stereocontrol of ring closure reactions involving coupling of radicals with anions.(b) Studies of radical structures and reactions:Electron paramagnetic resonance spectroscopy has been successfully applied to a study of the structures and rearrangement modes of highly strained polycyclic radicals, of carbamoyl radicals (aminoacyl radicals) iminyl and many other radicals.
