The allenic α-ketones 5a-f give, on irradiation in the presence of , the bis(tricarbonyliron) complexes 6a-f.In the case of ketone 5e, a minor bis(tricarbonyliron) complex with the proposed unique structure 8 is also obtained.Ketones 5a-d, which are disubstituted at C(4), under the same conditions, afford also the lactones 7a-d in moderate yields.The latter reaction is a new carbonyliron-mediated carbonyl insertion.The structure of the binuclear complexes 1a and 6e were established by X-ray crystallography.
