In this paper, three diiron butane-2,3-dithiolate complexes [Fe 2 (CO) 5 L{ µ -SCH(CH 3 )CH(CH 3 )S}] [L = P(4-C 6 H 4 F) 3 , 2 ; P(4-C 6 H 4 OCH 3 ) 3 , 3 ; P(3-C 6 H 4 Cl) 3 , 4 ] have been synthesized by CO substitution of the starting complex [Fe 2 (CO) 6 { µ -SCH(CH 3 )CH(CH 3 )S}] ( 1 ) with the corresponding monophosphine coligands in the presence of Me 3 NO·2H 2 O as the decarbonylating agent in 61‒74% yields. These complexes have been characterized by elemental analysis, IR, NMR spectroscopy, and single-crystal X-ray diffraction analysis. In addition, electrochemical studies revealed that these complexes can catalyze the reduction of proton to H 2 in the presence of acetic acid under the electrochemical conditions.
