Chemistry:Vinyl arsine

Short description: Organoarsenic compound

Vinyl arsine (C₂H₃AsH₂) is an organoarsenic compound and a primary arsine derivative featuring a vinyl group attached to an arsenic atom. It is primarily known in chemical research as a structural model for studying volatile primary arsines, and it relates closely to chlorovinylarsines like the military blister agent Lewisite.

Chemical Properties and HazardsStructure:

• Contains an arsenic-carbon double-bond-adjacent vinyl moiety (CH₂=CH-AsH₂).
• Toxicity: Organoarsenic and arsine compounds are highly toxic, targeting cellular functions, inducing hemolysis, and causing severe systemic damage.
• Reactivity: Highly reactive due to the presence of both the unsaturated vinyl functional group and the metaloid arsenic hydride center.
