The 2-Arsaethynolate Anion: Synthesis and Reactivity Towards Heteroallenes
The synthesis and isolation of the 2‐arsaethynolate anion, AsCO−, and its subsequent reactivity towards heteroallenes is reported. Reactions with ketenes and carbodiimides afford four‐membered anionic heterocycles in formal [2+2] cycloaddition reactions. By contrast, reaction with an isocyanate yiel...

Summary: | The synthesis and isolation of the 2‐arsaethynolate anion, AsCO−, and its subsequent reactivity towards heteroallenes is reported. Reactions with ketenes and carbodiimides afford four‐membered anionic heterocycles in formal [2+2] cycloaddition reactions. By contrast, reaction with an isocyanate yielded a 1,4,2‐diazaarsolidine‐3,5‐dionide anion and the unprecedented cluster anions As102− and As124−. These preliminary reactivity studies hint at the enormous potential synthetic utility of this novel anion, which may be employed as an arsenide (As−) source.
A look at As and Co.: Reported is the synthesis and isolation of the 2‐arsaethynolate anion, AsCO−, and its subsequent reactivity towards heteroallenes. Reactions with ketenes and carbodiimides afford four‐membered anionic heterocycles in formal [2+2] cycloaddition reactions. By contrast, reaction with an isocyanate yielded a 1,4,2‐diazaarsolidine‐3,5‐dionide anion and the unprecedented cluster anions As102− and As124−. |
