Abstract :
Reductive lithiation of α,α-dibromo esters using lithium naphthalenide afforded ester dianions leading to ynolate anions in good yields. Naphthalene-catalyzed reductive lithiation was also accomplished. This is a convenient, economical and practical method for the preparation of ynolate anions.
