Abstract

The syntheses of [ButPAs(NMe2)2K.pmedta]2 1 and [{CyNAs(NMe2)2K}2]∞ 2 from the reactions of [As(NMe2)3] with ButPH2 and CyNH2, respectively, in the presence of potassiated bases exemplify a general approach to multifunctional secondary phosphide and amide anions containing variable sets of group 15 donor centres.
