چکیده
Two independent pseudo-enanti-omeric mol-ecules comprise the asymmetric unit in the title compound, C(15)H(14)O(2). While the central O-C-C-C residue approaches planarity [torsion angles = -15.8 (3) (mol-ecule a) and 15.4 (3)° (mol-ecule b)], the benzene rings are approximately orthogonal [the dihedral angles formed between the benzene rings are 62.89 (12) (mol-ecule a) and 80.15 (12)° (mol-ecule b)]. Two-dimensional arrays in the ab plane sustained by O-H⋯O hydrogen bonding are found in the crystal structure.

In the title compound, C(21)H(16)O(2), the six crystallographically independent mol-ecules (Z' = 6) all exist in the enolized form. Strong intra-molecular hydrogen bonds are observed: one approximate H-atom-centered O⋯H⋯O hydrogen bond, two tautomeric forms O-H⋯O (three mol-ecules) and O⋯H-O (two mol-ecules). Only one weak inter-molecular C-H⋯O hydrogen bond between two neighboring mol-ecules i...

The title compound, C21H21NO, is a vinyl-ogous amide (enaminone) produced by reaction of 1-(2-phenyl-prop-2-en-1-yl)pyrrolidine-2-thione with phenacyl bromide. In the mol-ecule, the phenyl rings are twisted from the mean plane of the pyrrolidine ring by 11.2 (1) and 67.3 (1)°. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules related by translation along the b axis into chains.
