2,2-Dimethyl-5-triphenylmethyl-1,3-dioxane
The title compound, C(25)H(26)O(2), crystallizes with two crystallographically independent mol-ecules in the asymmetric unit. The differences between the two mol-ecules are marginal. The three benzene rings of each mol-ecule are in a propeller orientation and the 1,3-dioxane ring adopts a chair conformation.
متن کامل2,2-Dimethyl-5-[(2-nitroanilino)methylidene]-1,3-dioxane-4,6-dione
The crystal of the title compound, C(13)H(12)N(2)O(6), contains a bifurcated intra-molecular hydrogen bond between the N-H group and one of the O atoms from both the nitro group and the dioxane-4,6-dione moiety. In addition, mol-ecules are linked by a series of inter-molecular C-H⋯O secondary inter-actions. The dihedral angles between the benzene ring and the nitro group and the conjugated part...

The title compound, C(13)H(12)O(5), was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and 4-hy-droxy-benz-alde-hyde in ethanol. The 1,3-dioxane ring is in a distorted boat conformation. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(20) rings.

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 4-fluoro-benz-alde-hyde in ethanol. The 1,3-dioxane ring adopts an envelope conformation. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.
متن کامل2,2-Dimethyl-5-(2-naphthylaminomethylene)-1,3-dioxane-4,6-dione
There are two unique mol-ecules in the asymmetric unit of the title compound, C(17)H(15)NO(4), which are linked into chains via inter-molecular N-H⋯O and C-H⋯O inter-actions; the chains are linked via weak C-H⋯O inter-actions, forming a parallel sheet structure. The molecule is approximately planar, with dihedral angles of 19.91 (4) and 11.06 (4)° between the naphthyl ring and the amino-methyl-...
