N-Heterocyclic carbene-stabilised arsinidene (AsH)

Abstract

N-Heterocyclic carbene adducts of the parent arsinidene (AsH) were prepared by two different synthetic routes, either by reaction of As(SiMe3)(3) with 2,2-difluoroimidazolines followed by desilylation or by reaction of [Na(dioxane)(3.31)][AsCO] with imidazolium chlorides.
