buta13diyne

buta13diyne, also known as 1,3-butadiyne, is an organic compound with the chemical formula C4H2. It is a linear diyne, meaning it contains two triple bonds separated by a single bond. The molecule is symmetrical with the structure H-C≡C-C≡C-H.

1,3-butadiyne is a highly reactive molecule due to the presence of the conjugated triple bonds. It can undergo various addition reactions, polymerization, and cycloaddition reactions. Its reactivity makes it a useful building block in organic synthesis, particularly in the creation of more complex carbon frameworks.

The compound is typically prepared through dehydrohalogenation of dihalobutanes or by oxidative coupling of acetylene. It is a gas at room temperature and pressure, with a boiling point of -10.8 °C. Due to its reactivity and potential instability, it is often handled with care.

1,3-butadiyne has found applications in materials science, particularly in the synthesis of conjugated polymers and carbon-rich materials. Its ability to form extended pi systems makes it of interest for electronic and optical applications. Research also explores its potential in the synthesis of novel organic molecules and as a precursor for carbon nanomaterials.
