These processes were found to be first-order in the concentration of metal complex with the rates for dissociative loss of the olefinic ligands from ruthenium being much faster than their iron analogues. However, the ruthenium derivatives afforded formation of primarily mono-phosphine metal tetracarbonyls, whereas the ironcomplexes led largely to trans-di-phosphine tricarbonyls. This difference in behavior
Redox disproportionation of ironcarbonyls to carbonylferrate anions and Fe+, Fe2+ compounds occurs during the reaction of these carbonyls with both free azoles and their sodium salts. It is assumed that coordination of azole anion to ironcarbonyl takes place and that the species formed acts as a one-electron reducing agent towards iron, ironcarbonyl anion-radicals, detected by ESR, being formed

Abstract The interaction of ironcarbonyls, Fe(CO) 5 , Fe 2 (CO) 9 and Fe 3 (CO) 12 with Me 3 NO occurs according to a one-electron redox-disproportionation scheme giving rise to ironcarbonylradical anions: Fe 2 (CO) 8 ·− ( 1 ), Fe 3 (CO) 12 ·− ( 2 ), Fe 3 (CO) 11 ·− ( 3 ) and Fe 4 (CO) 13 ·− ( 4) . The role of Me 3 NO, inducing CO-substitution, consists of the generation of reactive 17-electron
