Details about the decarbonylation of compounds of the general class [Mo(sub 2-)Cp'(sub 2)(CO)(sub n)](n = 4 or 6) are given in the presence of dimethyl disulfide was controlled by the electron density on the metal varing with the substitution pattern of the Cp' cyclopentadienyl groups.

The asymmetric unit of the title compound, C26H30N2O4S, consists of two independent molecules, A and B, with similar conformations. In both molecules, the pyrrolidine and dihydropyran rings adopt envelope conformations, and are trans-fused; the tosyl group is attached to the pyrrolidine ring in a biaxial position and the sulfonyl group has distorted tetrahedral geometry. The A molecules are linked into a chain along the b axis by C—H⋯O hydrogen bonds, and the inversion-related molecules of adjacent chains are cross-linked into a two-dimensional network parallel to the bc plane via C—H⋯π interactions involving the pyridinone ring, and π-π interactions involving the benzene ring of the quinolinone ring system. A similar two-dimensional network is also formed by the B molecules. The centroid-centroid distances for the π-π interactions in the A and B molecules are 3.5477 (13) and 3.5743 (15) Å, respectively. The two-dimensional networks formed by the A and B molecules are arranged alternately along the a axis, and are linked via C—H⋯π interactions involving the sulfonyl-bound benzene ring of molecule B.

The pyrrolidine ring of the title molecule, C26H27ClN2O2S, adopts a twist conformation, while the tetrahydropyridine ring is in a half-chair conformation. The tosyl group is attached to the pyrrolidine ring in a biaxial position. The pyrrolidine and tetrahydropyridine rings are trans-fused. The pyridine-fused benzene ring forms dihedral angles of 73.95 (2) and 19.18 (5)°, respectively, with the benzene ring of the chlorobenzene and tosyl groups. The screw-related molecules are linked into a chain along the [010] direction by N—H⋯O hydrogen bonds, and the chains are cross-linked into a three-dimensional network by C—H⋯π interactions and weak π-π interactions [centroid-centroid distance = 3.7488 (5) Å].

The asymmetric unit of the title compound, C22H27ClN2O2S, consists of two independent molecules, A and B, with similar conformations. In both molecules, the pyrrolidine rings adopt twist conformations and the tetrahydropyridine rings have half-chair conformations; these rings are trans-fused. In molecule A, the tosyl group is attached equatorially to the pyrrolidine ring, whereas in molecule B it is in a biaxial position. In both molecules, the sulfonyl groups have distorted tetrahedral geometries. Molecules A and B are linked into a two-dimensional network parallel to the ab plane by N—H⋯O and C—H⋯O hydrogen bonds, and C—H⋯π interactions. [ABSTRACT FROM AUTHOR]

The title mol­ecule, C16H14O3, is slightly distorted from planarity, the dihedral angle between the two benzene rings being 9.51 (7)°. The configuration of the keto group with respect to the olefinic double bond is s- cis. O—H⋯O hydrogen bonds, and C—H⋯O and π–π interactions, link the mol­ecules to form a three-dimensional network. The C—H⋯O interactions form rings of graph-set motifs S(5), (6) and (7). [ABSTRACT FROM AUTHOR]

In the title mol­ecule, C15H11ClO2, the ketone group is in the s- cis conformation with respect to the olefinic double bond. The two aromatic rings form a dihedral angle of 26.07 (8)°. Screw-related mol­ecules are linked via O—H⋯O hydrogen bonds, forming a chain along the c axis. Weak C—H⋯O and C—H⋯Cl interactions interconnect the chains into a three-dimensional network.

The title mol­ecule, C15H11BrO2, is approximately planar and the dihedral angle between the two aromatic rings is 10.2 (2)°. The H atoms of the central enone moiety are trans. The mol­ecules form centrosymmetric hydrogen-bonded dimers via intermolecular O—H⋯O hydrogen bonds (H⋯O = 2.02 Å and O—H⋯O = 172°). [ABSTRACT FROM AUTHOR]
