Mechanistic studies on iridium catalyzed allylic substitution
Mechanistic studies on iridium catalyzed allylic substitution reactions catalyzed by iridium phosphoramidite complexes revealed that the active catalyst is generated through a base assisted cyclometalation of the phosphoramidite to form five-membered iridacycle. A mechanism for the reaction was …

Iridium (III) photosensitisers for photoredox catalysed carboxylation reactions of ketimines
… Subsequently, two mononuclear cationic bis-cyclometalated iridium(III) complexes (C1, C2) and a new trinuclear iridium(III) complex (C3) were synthesised. The complexes (C1-C3) were obtained as racemic mixtures (Λ, Δ isomers) which is an attribute of the helical chirality, inherent to these …
