The cationic iron η2-(α,ω-diene) complexes of the type. [(η5-C5H5)Fe(CO)2{η 2-(α,ω-diene)}]PF6, (diene = 1,3-butadiene: 1.4-pentadiene; 1.5-hexadiene; and 1.7-octadiene) were prepared by the reaction of η1-alkenyl compounds of the type [(η5C5H5)Fe(CO)2(η 1-alkenyl)] with the so-called trityl salt. (Ph3CPF6). The reactions of the η2-diene complexes with a number of nucleophiles give a range of products resulting from nucleophillic addition to the coordinated diene and/or displacement of the diene. The reaction with triethylamine results in deprotonation leading to the formation of [(η5-C5H5)Fe(CO)2(η 1-allyl)] complexes.
