Ethylenedioxy

In organic chemistry, ethylenedioxy is a functional group with the structural formula R−O−CH₂−CH₂−O−R'. It is often attached to an aromatic ring.

Examples:

• 3,4-Ethylenedioxythiophene, a precursor to conductive polymer
• 3,4-Ethylenedioxy-N-methylamphetamine, an analogue of MDMA with similar effects.
• (ethylenedioxy)dimethanol (OHCH₂−O−C₂H₄−O−CH₂OH), a biocidal formaldehyde releaser.

• 1,4-Benzodioxan
• 1,4-Benzodioxine
