Abstract On irradiation in the presence of Fe(CO) 5 , the allenic amides and imides showed a similar course of complexation to that of esters and lactones, respectively, e.g. the amides of type 10 led to diiron complexes of type 11 ( Scheme 3 ), whereas the imide 12 yielded a mixture of a dinuclear and two mononuclear complexes ( 13–15 , Scheme 4 ). The racemic ester 6 also gave mononuclear ( 7a , 7b , and 9 ) and dinuclear complexes (8 a and 8b ; Scheme 2 ). In case of the allenic acid 4 , only complexation of type 5 was observed ( Scheme 1 ).
