Abstract
Abstract We report herein the synthesis of a stable plumbylone ( 3 ) by reduction of a bromodigermylplumbylene ( 2 ) with 2.2 equiv of potassium graphite (KC 8 ). The molecular structure of 3 was established by a single‐crystal X‐ray diffraction study and features a two‐coordinated Pb center with an acute Ge−Pb−Ge bond angle. Computational studies showed that this complex ( 3 ) possesses a singlet electronic ground state with a Pb 0 center. Its high thermal stability can be most likely ascribed to the delocalization of π electrons over the Ge−Pb−Ge moiety. A preliminary reactivity study demonstrates that complex 3 can deliver Pb 0 atoms to an organic azide producing a tetrameric imido complex [(PbNDipp) 4 ] (Dipp=2,6‐ i Pr‐C 6 H 3 , 4 ) and perform a metathesis reaction with GeCl 2 ⋅dioxane to produce a bis(germylene)‐stabilized germylone ( 5 ), highlighting the synthetic utility of 3 .
