(E)-2-(3,5-Di-meth-oxy-benzyl-idene)indan-1-one.

ABSTRACT: The title chalcone, C₁₈H₁₆O₃, was prepared by a solventless base-promoted Claisen-Schmidt condensation and, upon recrystallization from ethanol, obtained in 56% yield. The dihedral angle between the indanone ring system and the benzene ring is 2.54 (4) ° and the C atoms of the methoxy groups deviate from the benzene ring by 0.087 (1) and 0.114 (1) Å. In the crystal, π-stacking is the predominant inter-molecular force, with the mol-ecules stacking into columns running parallel to the b axis of the unit cell.

6-Fluoro-indan-1-one.

Project description:The title compound, C9H7FO, crystallizes with two independent mol-ecules in the asymmetric unit, in which corresponding bond lengths are the same within experimental error. The five-membered ring in each molecule is almost planar, with r.m.s. deviations of 0.016 and 0.029 Å. In the crystal, mol-ecules form sheets parallel to (1 0 0) via C-H⋯O and C-H⋯F inter-actions with F⋯F contacts [3.1788 (16) and 3.2490 (16) Å] between the sheets.

5-Hy-droxy-indan-1-one.

Project description:In the title compound (5HIN), C(9)H(8)O(2), is perfectly planar as all atoms, except the H atoms of both CH(2) groups, lie on a crystallographic mirror plane. In the crystal, mol-ecules are linked by strong inter-molecular O-H⋯O hydrogen bonds, forming an infinite chain along [100], generating a C(8) motif.

4-Hy-droxy-indan-1-one.

Project description:The mol-ecule of the title compound, C(9)H(8)O(2), is essentially planar except for the methyl-ene H atoms [maximum deviation = 0.028 (1) Å]. In the crystal, the mol-ecules are linked by classical O-H⋯O hydrogen bonds and weak C-H⋯O inter-actions into chains along [110] and [1-10].

7-Meth-oxy-indan-1-one.

Project description:In the title compound, C(10)H(10)O(2), the 1-indanone unit is essentially planar (r.m.s. deviation = 0.028 Å). In the crystal, molecules are linked via C-H⋯O hydrogen bonds, forming layers lying parallel to the ab plane. This two-dimensional structure is stabilized by a weak C-H⋯π inter-action. A second weak C-H⋯π inter-action links the layers, forming a three-dimensional structure.

7-Hy-droxy-indan-1-one.

Project description:In the title compound, C(9)H(8)O(2), an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. The dihedral angle between the mean plane of the S(6) ring and the benzene ring is 1.89 (2)°. In the crystal, inversion-related mol-ecules are linked by pairs of O-H⋯O hydrogen bonds, forming a cyclic dimers with R(2) (2)(12) graph-set motif. Weak inter-molecular C-H⋯O(carbon-yl) and C-H⋯O(hy-droxy) hydrogen bonds link the dimers into chains along [010], generating two C(6) motifs that overlap three C atoms, forming R(2) (2)(8) ring motifs.

Plant-Mediated Enantioselective Transformation of Indan-1-one and Indan-1-ol. Part 2.

Project description:The main purpose of this publication was to obtain the S-enantiomer of indan-1-ol with high enantiomeric excess and satisfactory yield. In our research, we used carrot callus cultures (Daucuscarota L.), whereby the enzymatic system reduced indan-1-one and oxidized indan-1-ol. During the reaction of reduction, after five days, we received over 50% conversion, with the enantiomeric excess of the formed S-alcohol above 99%. In turn, during the oxidation of racemic indan-1-ol after 15 days, 36.7% of alcohol with an enantiomeric excess 57.4% S(+) remained in the reaction mixture. In addition, our research confirmed that the reactions of reduction and oxidation are competing reactions during the transformation of indan-1-ol and indan-1-one in carrot callus cultures.

Crystal structures of 6-chloro-indan-1-one and 6-bromo-indan-1-one exhibit different inter-molecular packing inter-actions.

Project description:The two title compounds are analogs of 1-indanone that are substituted at the 6-position with chlorine and bromine. Although very similar in mol-ecular structure, the crystal structures are not isomorphous and reveal that 6-chloro-indan-1-one, C9H7ClO (I), and 6-bromo-indan-1-one, C9H7BrO (II), exhibit unique inter-molecular packing motifs. The mol-ecules of the chloro analog (I) pack with a herringbone packing motif of C-H⋯O inter-actions, whereas the bromo derivative (II) packs with offset face-to-face π-stacking, C-H⋯O, C-H⋯Br and Br⋯O inter-actions. Compound (II) was refined as a two-component non-merohedral twin, BASF 0.0762 (5).

2-[(E)-2,5-Dimethoxy-benzyl-idene]indan-1-one.

Project description:In the title compound, C(18)H(16)O(3), the mean plane of the nine-membered indane system makes a dihedral angle of 3.71 (17)° with the benzene ring of the dimethoxy-phenyl group. The mol-ecular conformation is stabilized by intra-molecular C-H⋯O hydrogen contacts. The crystal structure is stabilized by inter-molecular C-H⋯O inter-actions, which link neighbouring mol-ecules into one-dimensional extended chains along the [100] direction. In the structure, C-H⋯π inter-actions are also observed.

Project description:In the title compound, C(16)H(11)BrO, the dihydro-indene ring system is approximately planar, with a maximum deviation of 0.008 (2) Å.
