Disease relevance of cyclopentane

• Pulmonary activation and toxicity of cyclopentadienyl manganese tricarbonyl [1].

High impact information on cyclopentane

• Structure-activity correlation in titanium single-site olefin polymerization catalysts containing mixed cyclopentadienyl/aryloxide ligation [2].
• The kinetics of the electrochemical reduction process has been studied, and the effects of varying the proton source, the solvent, the cyclopentadienyl substituents, and the sulfur substituents on the catalyst have been examined [3].
• Spin-localized cyclopentadienyl radical annelated with homoadamantene frameworks: isolation, X-ray crystal structure, and ESR characterization [4].
• To this end solvated salts MX2 (M = Fe, Ni, and Cr) were treated with a ligand that consisted of two doubly silyl-bridged cyclopentadienyl anions [5].
• Radical-molecule reactions for aromatic growth: a case study for cyclopentadienyl and acenaphthylene [6].

Biological context of cyclopentane

• Cyclization of 2 to heteroatom-containing cyclopentadienyl structures (6) competes with the Claisen-type rearrangement to acyclic, allenic structures [7].
• Sequential protonation and methylation of a hydride-osmium complex containing a cyclopentadienyl ligand with a pendant amine group [8].
• bis-cyclopentadienyl [Cp] complexes of vanadium(IV) or vanadocenes are rapid and potent inhibitors of human sperm motility with potential as a new class of contraceptive agents [9].
• Spectroscopic data suggest that the electron density at these disparate-metal-containing cluster cores is tunable by progressive (conceptual) cyclopentadienyl alkylation [10].
• No interaction between glutathione and titanocene dichloride was detected at pD 2, while at pD 5-7 competitive hydrolysis of the cyclopentadienyl ligands occurred [11].

Associations of cyclopentane with other chemical compounds

• Theoretical study of complexes of extended cyclopentadienyl ligands with zinc and cadmium [12].
• Structural parameters determined from the least-squares fit are the Fe-C bond lengths to the cyclopentadienyl rings, r(Fe-C)=2.047(4) A, and the distance between the carbon atoms of the cyclopentadienyl rings, r(C-C)=1.430(2) A and r(C1-C1')=1.46(1) A of ring carbon and aldehyde carbon atom [13].

Analytical, diagnostic and therapeutic context of cyclopentane

• When only one of the two cyclopentadienyl rings of the ferrocene unit is substituted, strong complexes are formed with beta-cyclodextrin in H2O, as demonstrated by liquid secondary ion mass spectrometry (LSIMS), 1H NMR spectroscopy, electrochemical measurements, and circular dichroism spectroscopy [14].
