2-(tert-Butoxy-carbonyl-amino)-2-(2-fluoro-phen-yl)acetic acid
Abstract:
The title compound, C(13)H(16)FNO(4), consists of conventional, centrosymmetric carboxyl-ate dimers. These dimers form infinite polymeric chains due to inter-molecular N-H⋯O hydrogen bonding. The 2-fluoro-phenyl unit is disordered over two sets of sites with an ocupancy ratio of 0.915 (3):0.085 (3).

IUPAC Nomenclature of Aldehydes
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 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.
