The 2-phosphaethynolate anion: convenient synthesis and the reactivity
Abstract
Since Becker and co-workers isolated the 2-phosphaethynolate anion (PC–O−) in 1992, the phosphorus-containing analogue of the cyanate ion (N
C–O−), the 2-phosphaethynolate anion has gained much attention because this anion is isoelectronic to small molecules such as O
C
S and F–C
P as well as the thiocyanate anion S
C
N−. This paper highlights the recently reported methods for the synthesis of 2-phosphaethynolate anions and its utilization in the synthesis of organophosphorus compounds, especially the interesting work reported by two independent groups of J. M. Goicoechea and H. Grützmacher.
