摘要

This work describes the synthesis and full characterization of elusive chloropnictenium ion salts of the type [Ar-R*N(SiMe) ECl][A] (Ar-R*=2,6-(CHPh2)-4-R-C6H2, R=Me, tBu; E=Sb, Bi; A=GaCl4, Al(OCH(CF3)(2))(4)). In these species the cation is significantly stabilized by weak arene interactions to flanking phenyl groups of the Ar-R* moiety. In this context the bonding situation has been studied by computational means and the reactivity towards the Lewis base 4-dimethylaminopyridine (dmap) was investigated.
