  • General Description 1,2-Pentadiene (also known as 1-Methyl-2,3-butadiene or Ethylallene) is an allene compound characterized by a cumulated diene structure with three contiguous carbon atoms forming two double bonds (C=C=C). It is a reactive hydrocarbon that can participate in various chemical reactions, including cycloadditions and polymerizations, due to its strained and conjugated system. The presence of the methyl and ethyl substituents influences its reactivity and physical properties, making it useful in synthetic organic chemistry. Its structure and behavior are distinct from conjugated dienes, often leading to unique reaction pathways.
