The reaction of N,N'-dimethyl-N,N'-bis(trimethylsilyl)urea with arsenic trichloride results in the formation of a heterocycle 2.The structure was established by X-ray analysis.The eight-membered ring has a boat conformation.Transannular interactions were observed between the arsenic and nitrogen atoms.The intramolecular As...As distance is 325.6 (1) pm.The pyrolysis of 2 yields the six-membered heterocycle 3.
