title: Direct access to [(Mes*P)2As](-), a 1,3-diphosphaarsa-2-allyl anion, isoelectronic with the allyl anion (Mes* = 2,4,6-(t)Bu3C6H2).
abstract: The reaction of As(NMe2)3 with Mes*PHLi provides a direct source of the 1,3-diphosphaarsa-2-allyl anion, [(Mes*P)2As](-) (isoelectronic with the allyl anion). The equilibrium between the E,E and E,Z isomers of this anion depends on the extent of Li(+) ion-pairing.
