SYNTHESIS OF ALLENIC NAPHTHALENE DERIVATIVES

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.
KEY WORDS: Isomerisation, Allenic derivatives of naphthalene
