Manganese cyclopentadienyl tricarbonyl

Similar set of experiments with a polycrystalline sample of cyclopentadi-enyl manganese tricarbonyl has shown very similar patterns of data to the above compound [18]. Longitudinal field relaxation of muons implanted into cyclopentadienyl manganese tricarbonyl was studied within the field range 0-400 mT at 300 K, and the temperature range 375-25 K at an applied field of 200 mT. The latter showed a relaxation maximum around 275 K, which was shown to be due to an Arrhenius process with an activation energy of

The compounds in this section can be divided into two categories those in which the heterocyclic group is a substituent on the metallocene, such as heterocyclic compounds containing cyclopentadienyl-manganese tricarbonyl, and those in which a heteroatom is in a ring of the metallocene, such as in azaferrocene.

The method is suitable for the determination of Mn, present as methyl-cyclopentadienyl manganese tricarbonyl, in gasoline in the range 0.5— 40/igml 1. The sample is reacted with bromine then diluted with MIBK and the standards prepared in a similar manner. This ensures an equal response from the Mn species in both sample and standard solutions.

An example of environmental speciation involves the determination of the manganese containing fuel additive, methylcyclopentadienyl manganese tricarbonyl (MMT), and its derivative, cyclopentadienyl manganese tricarbonyl (CMT). As discussed above, the toxicity of this compound and concerns about human exposure to inhaled manganese have raised concerns about the widespread use of this compound in gasoline. Instrumentation for this work (Figure 1) involved the combination of LC coupled with... 

An early organometallic molecule, tetraethyl lead, which was first made in Zurich by Lowig [80], was widely used for a period of time as a fuel addihve, unhl recognition of its effects on the environment and its implicahon in cases of environmental poisoning led to its prohibition [81]. The toxicology of (ri -methyl-cyclopentadienyl) manganese tricarbonyl (MMT) has also been studied it is a permissible fuel additive in some jurisdictions in North America. 

The initial idea in the preparation of complex 25 was to use tamoxifen as a vector for the potentially cytotoxic Cp2TiCl2 2 (section 2, this book). Preparation of complex 25, in which the aromatic p ring of tamoxifen is substituted by a Cp2TiCl2 entity, required development of a novel synthesis (Scheme 3.10) [72]. This synthesis starts with a McMurry coupling reaction between propionyl cyclopentadienyl manganese tricarbonyl 21 and the ketone 22, permitting preparation of the complex diphenyl-ethylene 23. This is converted to a cyclopentadienyl 24 via photochemical decomplexation, and immediately recomplexed in the presence of CpTiClj to give 25, which is isolated as the chloride.
