An Arsenic–Nitrogen Biradicaloid: Synthesis, Properties, and Reactivity

Abstract

As you like it: The first reported four-membered heterocycle [As(μ-NTer)]2, which can be referred to as a high-temperature stable biradicaloid, is formed, when a bulky substituent, such as the terphenyl group, prevents dimerization. Addition reactions of elemental sulfur and selenium (see scheme) as well as the double bond of CS2 demonstrate that [As(μ-NTer)]2 has radical-type behavior.
