This study details the crystal structure of C(24)H(22)O(4), revealing two independent molecules with transoid naphthalene ring systems. Weak C-H⋯O hydrogen bonds were observed in the crystal lattice.
Area of Science:
- Crystallography
- Organic Chemistry
- Molecular Structure
Background:
- Understanding the three-dimensional arrangement of atoms in organic molecules is crucial for predicting their properties and reactivity.
- The naphthalene moiety is a common structural motif in various organic compounds with diverse applications.
Purpose of the Study:
- To elucidate the crystal structure of the title compound, C(24)H(22)O(4).
- To analyze the molecular geometry, including dihedral angles and torsion angles, of the independent molecules.
- To identify intermolecular interactions within the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the crystal structure.
- The asymmetric unit was analyzed to identify independent molecules and their conformations.
- Geometric parameters such as dihedral and torsion angles were calculated.
Main Results:
- The asymmetric unit contains two independent molecules of C(24)H(22)O(4).
- Both molecules exhibit a transoid arrangement of their naphthalene ring systems, with dihedral angles of 83.0(1)° and 89.0(1)°.
- Slight variations were noted in the torsion angles of the methoxy-methoxy groups.
- Weak C-H⋯O hydrogen bonds were identified as the primary intermolecular interactions.
Conclusions:
- The crystal structure of C(24)H(22)O(4) has been successfully determined.
- The study provides detailed insights into the conformational preferences of the naphthalene ring systems and methoxy-methoxy groups.
- The presence of weak hydrogen bonds influences the crystal packing.

Phase II Reactions: Methylation Reactions
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
Structure and Nomenclature of Ethers
Ethers are organic compounds with an ether functional group which is characterized by an oxygen atom connected to two — identical or different — alkyl, aryl, or vinyl groups. The C–O–C linkage in dimethyl ether — the simplest ether — has an approximately tetrahedral bond angle of 110.3 degrees. The oxygen atom is sp3- hybridized, with the C–O distance being about 140 pm.
Classification of Ethers
Based on their attached substituent groups, ethers can be classified into two...
