Abstract The dicarbonyl(1,2-dimethylpentadienyl)triphenylphosphineiron(1+) cation ( 11 ) has been prepared from methyl 4-methyl-2 E ,4 E -hexadienoate in four steps. The cation ( 11 ) reacts with hydride and carbon nucleophiles in a regiospecific fashion to afford (3-methyl-2 E ,4 Z -diene)iron complexes. Dicarbonyl(3-methyl-7-nitro-2 E ,4 Z -heptadiene)triphenylphosphineiron ( 15 ), the product from the reaction
