Unolat

Unolat adalah golongan senyawa organik di mana sebuah atom oksigen bermuatan negatif menempel pada sebuah alkuna.[1] Unolat pertama kali disintesis pada 1975 oleh U. Schöllkopf and I. Hoppe melalui fragmentasi 3,4-difenilisoksazola menggunakan n-butillitium.[2] Ynolat bertindak sebagai prekursor dalam sintesis ketena.
