Abstract: The complexes 1,2,3,4,5,6-hexakis (σ-methylene) benzenedodecacarbonyltriiron (1) and 1,2,3,4,5,6- hexakis (σ-methylene tetracarbonylcobalt) benzene (3) have been synthesized by the reactions of 1,2,3,4,5,6-hexakis (bromomethyl)benzene with disodium tetracarbonylferrate and sodium tetracarbonylcobaltate, respectively. Complex 1 undergoes facile conversion into complex (2) where a a to π-conversion occurs with three Fe(CO)3 moieties separately coordinated to three butadiene fragments. Attempts to convert complex (3) into π-form are, however, unsuccessful.
