Deprotonated bridging dithiolate ligands in diiron carbonyl complexes of type 101 (R = H, Ph) rearrange intramolecularly by nucleophilic attack on an iron atom while an electron pair is displaced onto a sulfur atom with formation of an Fe—C bond in 102 (76). Neutral derivatives can be formed upon further alkylation, leading to type Ij complexes (Table 1). The bridg-... 

Various dithiaheterocyclic compounds fragment unsymmetrically in the presence of iron carbonyls to form bridging dithiolate ligands as in 172 (Table II). In contrast, UV irradiation of dithiane or trithiane in the... 

The ferrocenyl-bridged dithiolate zirconium diamide complex 116 is readily obtained from the reaction of the ferrocenyl dithiol ligand and Zr(NMe2)4116 (Equation (8)). Treatment of 116 with trimethylaluminum followed by exposure to ethylene in the presence of MAO yields solid polyethylene, but the catalyst activity is low and the polymer produced has a very broad molecular weight distribution. 

New complexes of the methylene-bridged dithiols Ph2P(S)CH2P(S)Ph2 and Ph2P(S)CH2P(S)Me2 have been prepared... 

The imidazohmn carbocation must be optimally positioned to extract a hydride from Ha, boimd to and activated by Fe° in [Fe]-Haase similarly, the other hydrogenases are well set up for cooperative interactions and the formation of iron hydrides. Positioned over the open site for the [FeFe]-Haase is the pendant nitrogen base built into the bridging dithiolate colactor. This pendant base is attractively available for rapid intramolecular shuttling of a proton into...
