Zusammenfassung
The primary stibanes RSbH:sub:2:/sub: (R = 2,4,6-(CH:sub:3:/sub:):sub:3:/sub:C:sub:6:/sub:H:sub:2:/sub:; 2-(Me:sub:2:/sub:NCH:sub:2:/sub:)C:sub:6:/sub:H:sub:4:/sub:) have been synthesized and structurally characterized. Reactions of secondary stibanes R:sub:2:/sub:SbH (R = C:sub:6:/sub:H:sub:5:/sub:, 2,4,6-(CH:sub:3:/sub:):sub:3:/sub:C:sub:6:/sub:H:sub:2:/sub:) with BuLi amounts the corresponding lithium diarylantimonides R:sub:2:/sub:SbLi. Treatment of the primary stibanes RSbH:sub:2:/sub: (R = C:sub:6:/sub:H:sub:5:/sub:, 2,4,6-(CH:sub:3:/sub:):sub:3:/sub:C:sub:6:/sub:H:sub:2:/sub:, 2-(Me:sub:2:/sub:NCH:sub:2:/sub:)C:sub:6:/sub:H:sub:4:/sub:, (Me:sub:3:/sub:Si):sub:2:/sub:CH) with BuLi, Na or K yields the Zintl compounds Sb:sub:7:/sub:M:sub:3:/sub: (M = Li, Na, K). From the reaction of :i:cyclo:/i:-(:sup:t:/sup:BuSb):sub:4:/sub: with alkali metals trinuclear :sup:t:/sup:Bu:sub:4:/sub:Sb:sub:3:/sub::sup:-:/sup:, dinuclear :sup:t:/sup:Bu:sub:3:/sub:Sb:sub:2:/sub::sup:-:/sup:, and mononuclear :sup:t:/sup:Bu:sub:2:/sub:Sb:sup:-:/sup: antimonides have been isolated. The synthesis of 2-(3 ,5 -dimethylphenyl)5,7-dimethylstibindolyl potassium was achieved in one pot reaction of trimesitylantimony with potassium.
