摘要：

Ynolates are carbanions having a triple bond in place of the double bond in enolate anions, For the past 20 years, several methods for the generation of ynolates hav been developed. Ynolates are ketene anion equivalents, thus ynolates introduce a ketene unit into substrates and the resulting products possess high reactivity. This allows ynolates to undergo unique reaction sequences. This review provides an overview of the syntheses and the reactions of ynolates including recent progress in the area.
