Bis(cyclooctatetraene)iron is an organoiron compound with the formula Fe(C8H8)2, abbreviated Fe(COT)2. It is an air-sensitive black solid that is soluble...

features two η8-COT ligands. In bis(cyclooctatetraene)iron (Fe(COT)2) one COT is η6 and the other is η4. (Cyclooctatetraene)iron tricarbonyl features η4-COT...

U(C8H4Ph4)2 and the cycloheptatrienyl species [U(C7H7)2]−. In contrast, bis(cyclooctatetraene)iron has a very different structure, with one each of a η6- and η4-C8H8...

not obvious from the formula. Ferrocene: bis(η5-cyclopentadienyl)iron Uranocene: bis(η8-1,3,5,7-cyclooctatetraene)uranium W(CO)3(PPri3)2(η2-H2): the first...

Tris(cyclooctatetraene)triiron or Fe3(COT)3, also referred to as the Lavallo-Grubbs compound (after its discoverers) is an organoiron compound with the...

hydrocarbons, e.g. cycloheptatriene, azulene, and bullvalene. In the case of cyclooctatetraene (COT), derivatives include Fe(COT)2, Fe3(COT)3, and several mixed...

"pentahapto". There are exceptions, such as uranocene, which has two cyclooctatetraene rings sandwiching a uranium atom. In metallocene names, the prefix...

(Benzylideneacetone)iron tricarbonyl, source of "Fe(CO)3". Mo(C7H8)(CO)3, a complex of cycloheptatriene. Fe(C8H8)2, a complex of cyclooctatetraene (Norbornadiene)molybdenum...

was the determination of the crystal structure of uranocene (di-π-(cyclooctatetraene)uranium). This structure was a seminal discovery in the study of f-block...

Pt(COD)2 is prepared by a more circuitous route involving the dilithium cyclooctatetraene: Li2C8H8 + PtCl2(COD) + 3C7H10 → [Pt(C7H10)3] + 2LiCl + C8H8 + C8H12...

during a catalytic cycle. For example, the cyclooctadiene ("cod") ligands in bis(cyclooctadiene)nickel(0) are labile. In some cases, dienes are spectator...

halide atom. Another organometallic complex is the golden-yellow bis(π-cyclooctatetraene) protactinium, or protactinocene (Pa(C8H8)2), which is analogous...

below). For nickel catalysis, formation of larger rings (particularly cyclooctatetraene) can be a problem. Alkyne trimerization is of no practical value,...

deprotonation of pentadiene. A number of complexes are known, including bis(pentadienyl) iron, Fe(C5H7)2, the "open" analog of ferrocene. Only few pentadienyl...
