Abstract

The first germanimidoyl chloride M^sFluind^tBu-Ge(Cl) [double bond, length as m-dash] NMes (2, where M^sFluind^tBu is a bulky hydrindacene skeleton) was synthesized through the reaction of M^sFluind^tBu-GeCl (1) and mesityl azide (MesN₃). In contrast, treatment of 1 with a less bulky azide ArN₃ (Ar = 4-^tBuC₆H₄) produced a germatetrazole chloride M^sFluind^tBu-Ge(Cl)N₄Ar₂ (3), and a salt [M^sFluind^tBu-GeN₄Ar₂]⁺[BAr^F₄]⁻ (4; Ar^F = 3,5-(CF₃)₂C₆H₃) followed by chloride abstraction with NaBAr^F₄, both bearing a five-membered GeN₄ ring. Functionalization of 2 with Ar′Li (Ar′ = 3,5-^tBu₂C₆H₃) or MeLi furnished a germanimine M^sFluind^tBu-Ge(Ar′) [double bond, length as m-dash] NMes (5) or an amide lithium salt M^sFluind^tBu-Ge(Me)₂-N(Mes)Li(thf) (6).
