Abstract

By the reaction of [Cp*Fe(η5-As5)] (I) (Cp*=C5Me5) with main group nucleophiles, unique functionalized products with η4-coordinated polyarsenide (Asn) units (n=5, 6, 20) are obtained. With carbon-based nucleophiles such as MeLi or KBn (Bn=CH2Ph), the anionic organo-substituted polyarsenide complexes, [Li(2.2.2-cryptand)][Cp*Fe(η4-As5Me)] (1 a) and [K(2.2.2-cryptand)][Cp*Fe{η4-As5(CH2Ph)}] (1 b), ...
