2-Bromo-1-(2-fluorophenyl)ethanone(CAS: 655-15-2)

2-Bromo-1-(2-fluorophenyl)ethanone is a crystalline solid with a molecular weight of approximately 215.02 g/mol. It is slightly soluble in water but more soluble in organic solvents like ethanol and acetone. Chemically, it is relatively stable but can undergo nucleophilic substitution reactions, particularly with alcohols and amines. The compound has a melting point of around 60-63°C and a boiling point of approximately 200°C. It reacts with bases to form bromide salts and with acids to generate ketone derivatives.

2-Bromo-1-(2-fluorophenyl)ethanone is typically synthesized via a reaction of 2-bromoethanone with 2-fluorophenylboronic acid in the presence of a palladium catalyst, such as Pd(PPh3)4, in the absence of oxygen. The reaction involves a cross-coupling process, leading to high selectivity and good yield. Other methods include the direct bromination of 1-(2-fluorophenyl)ethanone using bromine, although this approach may yield lower purity products.

2-Bromo-1-(2-fluorophenyl)ethanone finds applications in various industries, particularly in the pharmaceutical sector for the synthesis of complex organic molecules. It is also used in polymer chemistry for the modification of polymers, in the development of sensors for detecting specific chemicals, and in semiconductor manufacturing for the production of materials with unique electronic properties.

When handling 2-Bromo-1-(2-fluorophenyl)ethanone, it is crucial to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be handled carefully using absorbent materials, followed by proper disposal according to local regulations. Always refer to the safety data sheet (SDS) for detailed handling and disposal instructions.
