2-(5-Bromo-3-isopropyl-sulfanyl-1-benzofuran-2-yl)acetic acid
Abstract:
The title compound, C(13)H(13)BrO(3)S, was prepared by alkaline hydrolysis of ethyl 2-(5-bromo-3-isopropyl-sulfanyl-1-benzofuran-2-yl)acetate. In the crystal, the carboxyl groups are involved in inter-molecular O-H⋯O hydrogen bonds, which link the mol-ecules into dimers. These dimers are further packed into stacks along the c axis by inter-molecular C-H⋯π inter-actions, and by slipped π-π inter-actions between the furan rings of adjacent mol-ecules [centroid-centroid distance = 3.472 (2) Å, inter-planar distance = 3.398 (2) Å and slippage = 0.713 (2) Å].

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.
IUPAC Nomenclature of Aldehydes
IUPAC Nomenclature of Carboxylic Acids
For acyclic saturated monocarboxylic acids, the longest hydrocarbon chain containing the –COOH carbon is identified as the parent chain. Then, the last -e of the parent hydrocarbon name is replaced with a suffix -oic acid.
