1-Ethynyl-4-fluorobenzene

Description:

1-Ethynyl-4-fluorobenzene, with the CAS number 766-98-3, is an organic compound characterized by the presence of both an ethynyl group and a fluorobenzene moiety. It features a phenyl ring substituted with a fluorine atom at the para position and an ethynyl group (–C≡CH) at the first position. This compound is typically a colorless to pale yellow liquid or solid, depending on its state at room temperature. It is known for its aromatic properties, which contribute to its stability and reactivity. The presence of the ethynyl group introduces a triple bond, making it a useful building block in organic synthesis, particularly in the formation of more complex molecules through reactions such as cross-coupling. Additionally, the fluorine atom enhances the compound's lipophilicity and can influence its electronic properties, making it of interest in various applications, including pharmaceuticals and materials science. Safety precautions should be taken when handling this compound, as it may pose health risks if inhaled or ingested.
