Ynolates as functional carbanions

Ynolates are multifunctional carbanions bearing a triple bond. Due to the difficulty in synthesizing them, their chemistry has remained relatively unexplored. However, since the recent publication of several new methodologies for the preparation of these interesting compounds, the versatility of ynolates in synthetic organic chemistry has been recognized, and new aspects of ynolate chemistry, e.g., tandem reactions, cycloadditions, olefinations of carbonyl compounds, are being developed.
