A Gallium-Substituted Distibene and an Antimony-Analogue Bicyclo[1.1.0]butane: Synthesis and Solid-State Structures

摘要

RGa {R=HC[C(Me)N(2,6-iPr(2)C(6)H(3))](2)} reacts with Sb(NMe2)(3) with insertion into the SbN bond and elimination of RGa(NMe2)(2) (2), yielding the Ga-substituted distibene R(Me2N)GaSbSbGa(NMe2)R (1). Thermolysis of 1 proceeded with elimination of RGa and 2 and subsequent formation of the bicyclo[1.1.0]butane analogue [R(Me2N)Ga](2)Sb-4 (3).
