Abstract:
Pseudomonas mendocina MC2, able to use 9-fluorenone but not fluorene as its sole source of carbon and energy, was isolated. Identification of metabolites in growth media and washed cell suspensions indicated that strain MC2 metabolizes 9-fluorenone via angular dioxygenation of the ketone, to give 1,1a-dihydroxy-1-hydro-9-fluorenone, followed by the opening of the five-membered ring and further degradation of the resulting biphenyl derivative by reactions akin to those of biphenyl metabolism, which produce phthalate as an intermediate. The aim of this research was to study the biodegradation of

Abstract:
ABSTRACT Genes involved in the degradation of fluorene to phthalate were characterized in the fluorene degrader Terrabacter sp. strain DBF63. The initial attack on both fluorene and 9-fluorenone was catalyzed by DbfA to yield 9-fluorenol and 1,1a-dihydroxy-1-hydro-9-fluorenone, respectively. The FlnB protein exhibited activities against both 9-fluorenol and 1,1a-dihydroxy-1-hydro-9-fluorenone to produce 9-fluorenone and 2′-carboxy-2,3-dihydroxybiphenyl, respectively. FlnD is a heteromeric protein encoded by flnD1 and ORF16, being a member of the class III two-subunit extradiol dioxygenase. Fln

Abstract:
Oxygenated polycyclic aromatic hydrocarbons (OPAHs) are toxic and carcinogenic compounds widely present in the natural environment, posing a serious threat to the environment and human health. However, the removal of OPAHs is mainly hindered by their low water solubility. Cyclodextrins (CDs) are frequently used to form inclusion complexes (ICs) with hydrophobic molecules to improve their solubility. In this study, we investigated the solubility enhancement ability of different CDs on 9-fluorenone, a common OPAH, through phase solubility experiments. We successfully prepared three solid ICs of

Abstract:
Spirofluorenyl-1,2,4-oxadiazinan-5-ones are prepared in good to excellent yields through metal-free [3+3] cycloaddition of N-vinyl fluorenone nitrones and aza-oxyallyl cations under mild reaction conditions. Detailed studies reveal that N-vinyl fluorenone nitrones show greater reactivity in [3+3] cycloadditions with aza-oxyallyl cations compared to N-alkyl/aryl fluorenone nitrones. The spirofluorenyl-1,2,4-oxadiazinan-5-ones are easily prepared on gram scale. The present method features mild reaction conditions, broad substrate scope, good functional group tolerance and efficient [3+3] cycload

However, the compound 21 can not gelate in any solvents. Only the compound 20 can gelate in isopropanol at 0.13 w/w %, such low concentration called ”supergelators”.

We enumerate possible reaction paths, and determine the geometries of reactants, products and transition states. By calculating the single point energies with DFT and G2M(cc,MP2) methods along specific reaction paths, we plot the potential energy surface (PES). Based on these calculations, we identify the reaction pathways connecting to the three experimental observed products. The sec
