Fluoren-9-one oxime
نویسندگان
چکیده
In the title mol-ecule, C13H9NO, the fluorene system and the oxime group non-H atoms are essentially coplanar, with a maximum deviation from the fluorene mean plane of 0.079 (2) Å for the oxime O atom. A short intra-molecular C-H⋯O generates an S(6) ring. In the crystal, mol-ecules related by a twofold screw axis are connected by O-H⋯N hydrogen bonds, forming [100] chains Within these chains, mol-ecules related by a unit translation along [100] show π-π stacking inter-actions between their fluorene ring systems with an inter-planar distance of 3.347 (2) Å. The dihedral angle between the fluorene units of adjacent mol-ecules along the helix is 88.40 (2)°. There is a short C-H⋯π contact between the fluorene groups belonging to neighbouring chains.

A series of new C(2)-symmetric fluoren-9-ylidene malonate-derived bis(oxazoline) ligands were synthesized from fluoren-9-ylidene malonate and enantiomerically pure amino alcohols via a convenient route. Their asymmetric catalytic properties in the Friedel-Crafts reactions of indoles with arylidene malonates were evaluated, and the Cu(OTf)2 complex of a fluoren-9-ylidene malonate-derived bis(oxa...

The title compound, C(19)H(11)NO, is stabilized by one intra-molecular C-H⋯O hydrogen bond. The compound can be synthesized in good yield (49%), by transformation of functional groups [starting with 5-(fluoren-9-ylidenemeth-yl)furan-2-carbaldehyde]. The flourene and furan ring systems are nearly coplanar, with a dihedral angle of 6.36 (7)°.

An Arthrobacter sp. strain, F101, able to use fluorene as the sole source of carbon and energy, was isolated from sludge from an oil refinery wastewater treatment plant. During growth in the presence of fluorene, four major metabolites were detected and isolated by thin-layer chromatography and high-performance liquid chromatography. 9-Fluorenol, 9H-fluoren-9-one, and 3,4-dihydrocoumarin were i...
