Option 1

 * Article title: :Transition Metal–Free Ketene Formation from Carbon Monoxide through Isolable Ketenyl Anions
 * Article Evaluation:This paper describes the synthetic approaches to isolate ketenyl anion by using ylide phosphine compounds. They also demonstrates several reactivity studies with the isolated ketenyl anion to prove it as promising synthon for possible organic compound synthesis such as carboxylic acid and cyclobutane.

Option 2

 * Article title:Synthesis, Isolation and Application of a Sila-Ketenyl Anion.
 * Article Evaluation:This paper acknowledged the recent finding about ketenyl anion and added new synthetic route of synthesizing ketenyl anion via silicone anion. They also have done the computation study including NBO analysis to understand the electronic structure and charge distribution

Option 3

 * Article title:Stable Ketenyl Anions via Ligand Exchange at an Anionic Carbon as Powerful Synthons
 * Article Evaluation:They did a similar approaches as Gessner et al. to isolate the ketenyl anion by using the N2/CO exchange with NHC carbene. The isolated ketenyl anion was able to further functionalize and activate the bond. Their molecular structure was also analyzed in computation such as NBO analysis to support the stability of the ketene.

Option 4

 * Article title:Selectivity Control of the Ligand Exchange at Carbon in α-Metallated Ylides as a Route to Ketenyl Anions
 * Article Evaluation:Gessner et al. added new information about ketenyl anion that they published a year ago. They focused on substituent effect that affect the selectivity of the ketenyl anion product. They found out the electron-withdrawing group and Lewis acid metal can influence the preference of the ketenyl anion product when the ylide is not symmetrical. This paper adds structural studies on the ketenyl anion instead of finding new synthetic pathway to isolate it.
