<b>Synthesis of allenic naphthalene derivatives</b>

Abstract

Propargylic alcohol of naphthalene derivatives were synthesized and converted to the corresponding propargylic acetate using acetic anhydride. Reduction of the propargylic acetates by SmI2 afforded allenes and acetylenes. Base-promoted isomerisation of acetylene formed allene in high yield.
