Abstract:
The title compound, 5-methoxyspiro[tetracyclo[8.8.1.0(3,8).0(12,17)]nonadeca-3,5,7,12,14,16-hexene-19,2'-[1,3]dioxolane], C(22)H(24)O(3), exhibits a twin-chair conformation with the aromatic rings overlying each other. Comparison of the dihedral angle between these two rings with those from previously reported [3.3]orthocyclophanes of this type suggests the presence of a weak attractive charge-transfer interaction between the two, different, stacked arenes.

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.

Nomenclature of Carboxylic Acid Derivatives: Acid Halides, Esters, and Acid Anhydrides
The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.
