Transition Metal‐Free Activation of Carbon Monoxide: Ketenyl Anions by PPh3/CO Exchange

Ketenes (R2C=C=O) are important reactive intermediates in organic chemistry which are often challenging to access in stable form due to their polarized cumulenic structure and inherent high reactivity. Ketenyl anions (R(M)C=C=O) or metal ynolates (R−C≡C−OM) represent alternative, highly attractive s...
