2-(3-Bromo-4-meth-oxy-phen-yl)acetic acid

Area of Science:

• Organic Chemistry
• Crystallography

Background:

• 4-methoxyphenylacetic acid derivatives are important in organic synthesis.
• Understanding substituent effects on molecular structure is crucial.

Purpose of the Study:

• To synthesize and characterize a novel brominated derivative of 4-methoxyphenylacetic acid.
• To investigate the molecular structure and electronic properties of the synthesized compound.

Main Methods:

• Regioselective bromination of 4-methoxyphenylacetic acid using bromine in acetic acid.
• X-ray crystallography to determine molecular structure and crystal packing.
• Analysis of bond angles and substituent effects.

Main Results:

• The compound C(9)H(9)BrO(3) was synthesized with an 84% yield.
• Molecular structure analysis indicated near-planar methoxy group and a tilted acetic acid substituent.
• Electronic properties suggest an electron-withdrawing bromine atom and electron-donating methoxy and acetyl groups.
• Molecules form centrosymmetric hydrogen-bonded dimers in the crystal.

Conclusions:

• Successful synthesis and structural elucidation of a brominated 4-methoxyphenylacetic acid derivative.
• The study provides insights into substituent electronic effects and intermolecular interactions in the solid state.
