Generation of σ,π-furyl and thienyl ligands at di-iron centers via facile phosphorus-carbon bond cleavage: Synthesis and molecular structures of [Fe2(CO)6(μ-η1,η2-C4H3E){μ-P(C4H3E)2}] (E = O, S)

► Synthesis of di-iron furyl and thienyl complexes. ► Facile carbon-phosphorus bond cleavage. ► Radical-initiated mechanism. ► Tri-iron complexes also isolated but they are not intermediates.
