dialkylarsanyl

Dialkylarsanyls are organoarsenic compounds with the general formula R2AsR', where R and R' are alkyl groups. These compounds are characterized by a trivalent arsenic atom bonded to two alkyl substituents and a third organic group. The structure can be viewed as analogous to phosphines, where phosphorus is replaced by arsenic. Dialkylarsanyls are typically liquids or low-melting solids and are often volatile. Their reactivity is influenced by the arsenic atom, which can undergo oxidation and nucleophilic attack. They are often used as ligands in coordination chemistry, forming complexes with transition metals. These complexes find applications in catalysis and materials science. Some dialkylarsanyls can also serve as precursors in the synthesis of other organoarsenic compounds or in the deposition of arsenic-containing thin films. Due to the toxicity associated with many arsenic compounds, dialkylarsanyls should be handled with caution in well-ventilated areas, and appropriate safety measures should be employed. Their study contributes to understanding the chemistry of p-block elements and the development of new functional materials.
