6-Hydroxy-2H-1,3-benzodioxole-5-carbaldehyde
The title compound, C(8)H(6)O(4), crystallizes with two independent mol-ecules in the asymmetric unit. The benzodioxole ring system is almost planar in each mol-ecule, with maximum deviations of 0.008 (1) and 0.007 (1) Å. The mol-ecular structure is characterized by strong electrostatic intra-molecular O⋯O contacts [2.649 (3) Å] and intra-molecular O-H⋯O hydrogen-bonding inter-actions. Inter-mo...
متن کامل6-Methoxymethoxy-7-trifluoromethyl-1,3-benzodioxole-5-carbaldehyde
The title compound, C(11)H(9)F(3)O(5), crystallizes with three mol-ecules in the asymmetric unit. One -CF(3) group is disordered by rotation, with the F atoms split over two sets of sites with occupancies which converged to 0.888 (6) and 0.112 (6). Weak π-π inter-actions are observed between adjacent benzene rings [the shortest centroid-centroid distance is 3.8858 (4) Å], resulting in the forma...

The asymmetric unit of the title hydrazone compound, C(15)H(10)BrClN(2)O(4), contains two independent mol-ecules. The dihedral angles between the benzene rings are 38.7 (3)° in one mol-ecule and 24.3 (3)° in the other. Both mol-ecules exist in trans conformations with respect to the C=N double bonds of the central methyl-idene units. Intra-molecular O-H⋯N contacts are observed in both mol-ecule...
متن کاملMethyl 6-bromo-7-methoxy-1,3-benzodioxole-5-carboxylate
The non-H atoms of the title compound, C(10)H(9)BrO(5), are essentially coplanar, with the exception of the ester group [the O=C-O-C torsion angle is -143.4 (3)°].
متن کامل1-(5-Hydroxy-7-methoxy-2,2-dimethyl-2H-chromen-6-yl)ethan-1-one
The title chromene, C(14)H(16)O(4), was isolated from the stems of Polyalthia plagioneura Diels. The mol-ecular structure is stabilized by an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, the mol-ecules are linked by C-H⋯O inter-actions, generating [010] chains.
