Contributions to the Chemistry of Boron, CIII. A Dimeric Diazastannaboretidine: Preparation, Dynamic Behaviour, and Molecular Structure(CH3)2B-N(CH3)Li and SnCl2 yield unstable Sn[NCH3-B(CH3)2]2; however, the reaction of SnCl2 with (CH3)3Si-NLi-B(CH3)2 leads to the dimeric diazastannaboretidine 4b with elimination. of B(CH3)3. 4b shows fluctuating behaviour at 〉60°C. According to its X-ray structure, 4b possesses a tricyclic tub form structure built from three condensed four-membered rings.
Notes:
(CH3)2B-N(CH3)Li und SnCl2 liefern instabiles Sn[NCH3-B(CH3)2]2, während die Umsetzung von SnCl2 mit (CH3)3Si-NLi-B(CH3)2 unter B(CH3)3-Abspaltung zu dem dimeren Diazastannaboretidin 4b führt. Dieses System zeigt oberhalb von 60°C fluktuierendes Verhalten. Nach einer Röntgenstrukturanalyse besitzt 4b eine tricyclische, aus drei Vierringen bestehende Wannen-struktur.
