Photoisomerisation of the diiron carbonyl species on the acenaphthylene ligand: the first photo-directed ‘switching’ of the coordination site of bimetallic species on aromatic hydrocarbons
Abstract
Irradiation of (µ2-η3 : η5-acenaphthylene)Fe2(CO)51 gave a novel metastable haptotropic isomer 2(X-ray structure supported), which regenerated 1 in solution upon keeping in the dark.
