In the title compound, C12H16FNO2, the dioxane ring adopts a chair conformation with the methyl substituents and the C - N bond in equatorial orientations. Its mean plane subtends a dihedral angle of 40.17(6)° with the benzene ring. In the crystal, weak N - H⋯F hydrogen bonds link the molecules into C(7) chains propagating in [100].

In the title compound, C12H16BrNO2, the dioxane ring adopts a chair conformation and its mean plane makes a dihedral angle of 60.63 (12)° with the 4-bromophenyl ring. In the crystal, molecules are linked by pairs of N - H⋯O hydrogen bonds, forming inversion dimers with an R 2 2(8) ring motif. These dimers are consolidated by pairs of C - H⋯O hydrogen bonds with an R 2 2(16) ring motif. Adjacent dimers are connected via C - H⋯O hydrogen bonds, forming infinite chains propagating along the c-axis direction.

In the title compound, C13H19NO2, the dioxane ring adopts a chair conformation and its mean plane makes a dihedral angle of 45.36 (8)° with the phenyl ring. In the crystal, molecules are linked by pairs of N - H⋯O hydrogen bonds, forming inversion dimers with R 2 2(12) ring motifs. These dimers are consolidated by pairs of C - H⋯O hydrogen bonds with R 2 2(8) ring motifs.

In the title compound, C12H16FNO3, the dioxane ring adopts a chair conformation with the methyl groups and amine N atom in equatorial positions. The best plane through the dioxane ring makes a dihedral angle of 43.16 (8)° with the phenyl ring. In the crystal, pairs of C - H⋯O hydrogen bonds link the molecules into centrosymmetric R 2 2(8) dimers, which are linked into [100] chains by further C - H⋯O hydrogen bonds. The N - H group does not participate in hydrogen bonding.

In the title compound, C13H19NO3, the dioxane ring adopts a chair conformation. Its mean plane is inclined to the 4-methoxyphenyl ring by 70.34 (9)°. In the crystal, molecules are linked by pairs of C - H⋯O hydrogen bonds, forming inversion dimers with an R 2 2(16) ring motif. The dimers are linked via C - H⋯π interactions, forming two-dimensional networks lying parallel to the ac plane. © 2013 Fatima et al.

The synthesis of 1,2-disubstituted benzimidazoles by the reaction of an o-phenylenediamine and various aromatic aldehydes in the presence of Indion 190 resin was reported. In a 50 mL, round-bottom flask, o-phenylenediamine and an aromatic aldehyde were stirred in the presence of Indion 190 in an acetonitrile at 50-60°C temperature. The reaction progress was monitored by TLC. After completion of the reaction the reaction mixture and catalyst were separated by filtration. The filtrate was concentrated under reduced pressure to furnish the crude product, which was further purified by column chromatography. The catalyst was washed with water, activated and reused for fresh reactions. The conversion was significantly increased to 96% within shorter time by adding 0.100 g of the catalyst in acetonitrile. The catalyst was recovered, activated and reused for consecutive times without loss of selectivity.
