(3E,5E)-1-Benzyl-3,5-bis-(2-fluoro-benzyl-idene)piperidin-4-one.

ABSTRACT: The inversion-related mol-ecules of the title compound, C(26)H(21)F(2)NO, associate into closed dimeric subunits via co-operative C-H⋯π inter-actions. Two non-classical C-H⋯O and one C-H⋯N intra-molecular hydrogen bonds are also found in the crystal structure. The piperidin-4-one ring adopts a sofa conforamtion with the 1-benzyl group in the equatorial position, and the equiplanar fluoro-phenyl substituents in the 3- and 5-positions stretched out on either side. The 1-benzyl group is disposed towards the substituent in the 6th position of the piperidin-4-one ring. The 3,5-diene units possess E configurations.

Project description:In the title compound, C(22)H(17)Cl(2)NO(2), the asymmetric unit consists of two crystallographically independent mol-ecules and each piperidinone ring adopts an envelope conformation. The dihedral angles between the two chloro-benzene rings are 24.81 (10) and 19.15 (8)° in the two mol-ecules. In the crystal, mol-ecules are connected via weak inter-molecular C-H⋯O hydrogen bonds forming layers perpendicular to the a axis.

(3E,5E)-3,5-Bis(4-allyl-oxybenzyl-idene)-1-benzyl-piperidin-4-one.

Project description:In the title compound C(32)H(31)NO(3), the all-yloxy groups on either side of the piperidin-4-one ring are conformationally disordered. The contribution of major and minor components of the allyloxy group at the 3rd position of the ring are 0.576 (4) and 0.424 (4), respectively, and those at the 5th position are 0.885 (3) and 0.115 (3), respectively. The six-membered piperidin-4-one ring adopts a sofa conformation with the benzyl group occupying an equatorial position and the olefinic double bonds possessing an E configuration. Flanking phenyl substituents are stretched out on either side of the six-membered ring. π-π inter-actions with a centroid-centroid distance of 3.885 (1) Å give rise to mol-ecular dimers and short C-H⋯π contacts lead to chains along the c axis.
