Synthesis and Characterization of Diiron Thiadithiolate Complexes Related to the Active Site of [FeFe]-Hydrogenases
On the basis of preparation of the known complex [Fe2(mu SCH2)2S(CO)6] (A) by a new method involving condensation of [(mu-LiS)2Fe2(CO)6] with excess S(CH 2Br)2, twelve new diiron thiadithiolates as mimics of the [FeFe]-hydrogenase active site have been synthesized by substitution of the CO ligand and coordination at the central S atom of complex A with appropriate reagents. Treatment of A with 1. equiv. of the monodentate ligands PPh 3 and [(eta5-C5.H5) (eta5-Ph2PC5H4)Fe] in the presence of Me3NO and with 1 equiv.tBuNC and cyclohexyl isocyanide gave the single [2Fe3S]-cluster-containing monosubstituted complexes [Fe2(U-SCH2J2S(CO) 5(L1)] (1, L1 = PPh3; 2, L1 = (eta5-C5H5) (eta5Ph 2PC5H4)Fe; 3, L1 = tBuNC; 4, L 1 = C6H11NC), whereas the double [2Fe3S]cluster-containing disubstituted complexes [(Fe2(mu-SCH 2)2S(CO)5}2(L2)] [5, L2 = 4,4′-(Ph2P)2(C6H 4)2; 6, L2 = trans-Ph2PCH=CHPPh 2; 7, L2 = 1,4-(CN)2C6H4; 8, L2 = (eta5-Ph2PC5H 4)2Fe; 9, L2 = (eta5-Ph 2PC5H4)2Ru] were produced by reaction of A with 0.5 equiv. of the corresponding bidentate ligands in the presence of Me3NO. In addition, the single [2Fe3S]-cluster-containing complexes in which the central S atom is coordinated, [{Fe2(mu- SCH2)2S(CO)6}[(eta5-MeC 5H4)(CO)2Fe}(BF4)] (10), [(Fe 2(mu-SCH2)2S(CO)6 }{Cr(CO) 5}] (11), and [(Fe2(muSCH2) 2S(CO)6}[W(CO)5}] (12), could be obtained by reaction of complex A with the in situ prepared. [((mu5-MeC 5H4)(CO)2Fe)(BF4)], [Cr(CO) 5(thf)], and [W(CO)5;(thf)], respectively. While complex 3 was found to be able to reduce the proton of the weak acid Et3NHCl to give H2, the X-ray crystallographic study confirmed that (i) each P atom of the phosphane ligands in 1 and 8 occupies an apical position at the Fe atoms, (ii) the isocyanide ligand in 3 lies in a basal position of the Fe atom, and (iii) the (eta5MeC5H4)(CO) 2Fe, Cr(CO)5, and W(CO)5 units in 10-12 are linked to the central S atom of complex A by an equatorial bond from the two fused sixmembered rings of their [2Fe3S]-cluster cores.
