Phosphaethynolate
WebAccompanied by the release of CO 2, Na 2 (P 2 C 3 O 4) reacts with both 2-iodopropane and 4,4′,4′′-trimethoxytriphenylmethyl chloride to form four-membered cyclic anions. For comparison the analogous reactions were performed with Na (OCP) instead of Na 2 (P 2 C 3 O 4) and the results are discussed in detail. WebSince Becker and co-workers isolated the 2-phosphaethynolate anion (P C–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 …
