The reaction of Fe 3 (CO) 12 ( 13 ) with 7,8‐dithiabicyclo[4.2.1]nona‐2,4‐diene 7‐ exo ‐oxide ( 12 ) yields the sulfenato‐thiolato complex 14 , which is used as starting material for further reactions. The disulfenato complex 17 is obtained by using one equivalent of dimethyldioxirane (DMD), and the monoepoxide 18 is prepared by the oxidation of 14 with an excess of DMD. Complex 14 can be converted to the monophosphine complexes 19a and 19b by subsequent substitution of one CO ligand using trimethylaminoxide Me 3 NO and triphenylphosphine PPh 3 . Additional substitution reactions are done with 17 by using acetonitrile as a ligand to form 20a and 20b . In the electrochemical part of the paper, the reactions of the reduced iron species 14 , 15 , 17 , and 19a are studied.
