Reaction of 2,4,6-tris(trifluoromethyl)phenyldichloroarsane with potassium 2,4,6-tris(trifluoromethyl)anilide 1 yields As,N-bis(2,4,6-tris(trifluoromethyl)phenyl)iminoarsane, 3, and As,N,N‘-tris(2,4,6-tris(trifluoromethyl)phenyl)diaminoarsane, 4. The first X-ray structural analysis of a compound containing a CNAsC bonding unit shows the monomeric character of 3.
