The synthesis of iridium(III) complexes containing bulky porphyrin ligands is described. The chiraliridium(III) complex of the D4-symmetric Halterman porphyrin ligand [Ir((+)-D4-Por)Me(L)] (L = solvent) is an effective catalyst for enantioselective intramolecular carbene insertion into saturated C–H bonds of α-diazoesters, giving the corresponding cis-β-lactones in good isolated yields (up to 87%)

Aryldiazoacetates can undergo photolysis under blue light irradiation (460–490 nm) at room temperature and under air in the presence of numerous trapping agents, such as styrene, carboxylic acids, amines, alkanes and arenes, thus providing a straighforward and general platform for their mild functionalization.
