Ethyl 2-(4-benzoyl-2,5-dimethyl­phen­oxy)acetate

The title compound, C19H20O4, was synthesized via a Fries rearrangement of hydr­oxy benzophenone. The dihedral angle between the least-squares planes of the two benzene rings is 69.04 (11)°. The mol­ecular structure displays an intra­molecular non-classical C—H⋯O hydrogen bond

N-{3-[2-(4-Fluoro­phen­oxy)eth­yl]-2,4-dioxo-1,3-diaza­spiro­[4.5]decan-7-yl}-4-meth­oxy­benzene­sulfonamide

In the title compound, C23H26FN3O6S, the two terminal aromatic rings form a dihedral angle of 49.26 (12)°. The cyclo­hexane ring adopts a chair conformation and the five-membered ring is essentially planar, with a maximum deviation from planarity of 0.0456 (19) Å. The dihedral angles between the five-membered ring and the meth­oxy­benzene and fluoro­benzene rings are 33.56 (11) and 81.94 (12)°, respectively. The crystal structure displays N—H⋯O hydrogen bonds as well as weak inter­molecular C—H⋯O inter­actions

(7-chloro-2-oxo-2H-chromen-4-yl)methyl diethylcarbamodithioate

In the title compound, C15H16ClNO2S2, the 2H-chromene ring system is nearly planar, with a maximum deviation of 0.023 (2) A˚ . In the crystal, C—HO hydrogen bonds give R2 1 (7) motifs, which generate [100] chains. C—H and – interactions between chromene moieties [shortest ring centroid–centroid distance = 3.6199 (13) A˚ ] consolidate the packin

3-(2-Bromoacetyl)phenyl benzoate

In the title compound, C15H11BrO3, the dihedral angle between the benzene rings is 72.59 (6)°. In the crystal, pairs of C—H...π contacts form inversion dimers. Additional C—H...O hydrogen bonds generate R21(6) ring motifs and stack these dimers along the b axis. Short intermolecular Br...O contacts of 3.254 (3) Å are also observed and link the stacks into a three-dimensional network
