Molecular structure of ynolates.

Ynolates are chemical compounds with a negatively charged oxygen attached to an alkyne functionality.[1] They were first synthesized in 1975 by Schöllkopf and Hoppe via the n-butyllithium fragmentation of 3,4-diphenylisoxazole.[2]

Synthetically, they behave as ketene precursors or synthons.
