3-Ethynylpyridine

Description:

3-Ethynylpyridine is an organic compound characterized by the presence of a pyridine ring substituted with an ethynyl group at the 3-position. Its molecular formula is C8H7N, and it features a triple bond between the carbon atoms of the ethynyl group, contributing to its reactivity. This compound is typically a colorless to pale yellow liquid with a distinctive odor. It is soluble in organic solvents such as ethanol and ether but has limited solubility in water due to the hydrophobic nature of the ethynyl group. 3-Ethynylpyridine is known for its applications in organic synthesis, particularly in the preparation of various pharmaceuticals and agrochemicals. The presence of the nitrogen atom in the pyridine ring imparts basic properties, allowing it to participate in various chemical reactions, including nucleophilic substitutions and coupling reactions. Additionally, it can act as a ligand in coordination chemistry, forming complexes with transition metals. Safety precautions should be taken when handling this compound, as it may pose health risks if inhaled or ingested.
