(Ethynyloxy)benzene, also known as phenylethyne or phenylacetylene, is an organic compound characterized by the presence of both an ethynyl group and a phenyl group. Its molecular structure features a benzene ring bonded to an ethynyl group (-C≡C-H), which imparts unique properties to the compound. This substance is typically a colorless to pale yellow liquid with a distinct aromatic odor. It is known for its reactivity, particularly in coupling reactions, making it valuable in organic synthesis and materials science. The compound is relatively insoluble in water but soluble in organic solvents, which enhances its utility in various chemical applications. Additionally, (ethynyloxy)benzene exhibits properties typical of alkynes, such as acidity due to the presence of the terminal alkyne hydrogen. Safety considerations are important when handling this compound, as it can be flammable and may pose health risks if inhaled or ingested. Overall, (ethynyloxy)benzene serves as a significant building block in the synthesis of more complex organic molecules.
