Abstract

The low-temperature reactions of [Sb(NMe2)3] with [CyPH2] and [CyPHNa] (1:1:1 equiv.) and of [As(NMe2)3] with [tBuPHLi] (1:3 equiv.) in TMEDA-thf [TMEDA = Me2NCH2)2] produce [{cyclo-(CyP)4Sb)Na·Me2NH·TMEDA]2 1 and [(cyclo-(tBuP)3As}Li·TMEDA·thf] 2, respectively; at higher temperatures these reactions generate Zintl compounds containing Sb73- and As73- anions.
