The title compound, C(15)H(11)BrO(2), exists as a diketone in which the two benzoyl groups are nearly perpendicular to each other [dihedral angles = 79.9 (1) and 87.4 (1)° in the two independent mol-ecules].

The title compound, C(10)H(6)O(4), lies across a twofold rotation axis through the midpoint of the C-C bond between the two carbonyl groups. The furan ring plane and the plane through all atoms are inclined at 23.88 (1)°. In the crystal structure, weak C-H⋯O hydrogen bonds form sheets in the bc plane and columns down the c axis.

The title compound, C(14)H(13)BrN(2)OS, was synthesized from the multicomponent reaction between thio-urea, 4-bromo-benzaldehyde and cyclo-hexane-1,3-dione. The crystal packing is stabilized by inter-molecular N-H⋯O, N-H⋯S, C-H⋯O and C-H⋯S hydrogen bonds. Br⋯O inter-actions [3.183 (3) Å] are also observed in the crystal structure.

The title compound, C(13)H(11)FO(4), was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and 2-fluoro-benzaldehyde in ethanol. In the crystal structure, mol-ecules are linked into chains by weak inter-molecular C-H⋯O hydrogen bonds.

In this study, a new series of 6-amino-1,3-dimethyluracil derivative with 6-(3-substituted N-benzylidene)-1,3-dimethyl pyrimidine-2,4-dione-6-yl derivatives which were synthesized by using one pot synthesis.

The title compound, C(16)H(8)O(3), was synthesized by the Pd-coupling reaction of phenyl-acetyl-ene with 4-bromo-phthalic anhydride. The phenyl and isobenzofurane rings are nearly coplanar, forming a dihedral angle of 6.70 (10)°. In the crystal structure, centrosymmetrically related mol-ecules are linked into dimers by C-H⋯O hydrogen bonds.
