Reaction of an arsinoamide with chloro tetrylenes: substitution and As–N bond insertion

Abstract

Reaction of the arsinoamide [(Mes₂AsNPh){Li(OEt₂)₂}] with the low-valent group 14 compounds, [{PhC(^tBuN)₂}ECl] (E = Si, Ge) and GeCl₂·dioxane, resulted in two different reaction pathways: simple substitution or substitution accompanied by an insertion step. As a result, either insertion products with an As–SiN unit and an As–Ge bond, or substitution products, in which the intact arsinoamide binds to the group 14 elements via the N atom, were obtained.
