Abstract

The known cyclic dimer, (Me₃SiNSiMe₂)₂ (1), was isolated in the reaction of GaCl₃ with one equivalent of Li[N(SiMe₃)₂] at room temperature as the result of cleavage of a Si-C bond from the N(SiMe₃)₂ anion. Although the gallium product was not isolated from the GaCl₃ reaction, pyrolysis of the new base-stabilized dichloro(silyl)amido gallium compounds, Cl₂Ga[N(SiMe₃)₂](quin) (2) (quin = quinuclidine), Cl₂Ga[N(SiMe₃)₂](NMe₃) (3), Cl₂Ga[N(SiMe₃)(^tBu)](quin) (4) and was monomeric with the gallium atom adopting a distorted tetrahedral geometry. Improved structural data for 1 are also reported.
