N2  - In the reaction of N,N'-bis-trimethylsilyl-dimethylurea with As[N(CH3)2]3 a four membered ring O = 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)2ASCl 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(OSO2CF3)2 3. 1H, 19F NMR as well as mass spectroscopy have been used in the characterization of the products obtained.
