 Title    Arsenhaltige Heterocyclen Heterocycles Containing Arsenic  
 Abstract    In the reaction of N,N'-bis-trimethylsilyl-dimethylurea with As[N(CH3)2]3 a four membered ring 0 = C(NCH3)2AsN(CH3)2 1 could be isolated. 1 was not obtained by cleavage of the Si-N-bonds with the corresponding chloride. In contrast CH3N[CONCH3Si(CH3)3]2 reacts with AsCb to yield the six-membered ring CH3N(CON-CH3)2ASC1 2. The four-membered ring which contains an arsenic-halogen bond seems to be unstable. In the adamantane-type compound, AS4(NCH3)6, one methylamine could be eliminated by CF3SO3H to give AS4(NCH3)5(OS02CF3)2 3. X H, 19 F NMR as well as mass spectroscopy have been used in the characterization of the products obtained.
