(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.

(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.
