 Title    Cyclische Diazastannylene, IV 1 Zur Oxidation von 1.3-Di-ferf-butyl-2.2-dimethyl- 2 -diazasilastannetidin Oxidation of l,3-Di-£erJ-butyl-2,2-dimethyl-1,3,2,4A 2 -diazasilastannetidine  
 Abstract    The reactions of l,3-di-<er^-butyl-2,2-dimethyl-l,3,2,4A 2 -diazasilastannetidine (1) with O2 and Sß or SnCU proceed in two steps: In a first redoxtype reaction an intermediate containing tetravalent tin is formed. Some of these intermediates are unstable with respect to the starting material stannylene 1 and undergo a substitution reaction to yield a spiro-tetraazastannane. Under appropriate conditions the intermediate from the sulfur-and SnCLi-reaction can be isolated and turns out to be either dispiro[3,3,3]distanna-disulfa-disila-tetrazane or a diaza-dichlorostannane respectively. Crystal and kinetic data of some products/reactions are reported.
