posted on 2005-11-28, 00:00 authored by Sven-Oliver Hauber, Mark NiemeyerThe one-pot transmetalation/deprotonation reaction of the bulky
triazene Dmp(Tph)N3H with bis(pentafluorophenyl)mercury and
europium or ytterbium affords the structurally characterized
unsolvated metal(II) pentafluorophenyl triazenides [Dmp(Tph)N3MC6F5] (M = Eu, Yb; Dmp = 2,6-Mes2C6H3 with Mes = 2,4,6-Me3C6H2; Tph = 2-TripC6H4 with Trip = 2,4,6-iPr3C6H2) or,
depending on the molar ratio, the solvated complex [Dmp(Tph)N3YbC6F5(THF)].
