Cl (V), 3>Cl (VII) and the 1,3,5-trithiacyclohexane derivative (CHS)3(CH2CH2Cl)3 (IX) react with NaAs(C6H5)2 in liquid ammonia to give N2CH2CH(CH3)As(C6H5)2 (VI), N3 (VIII) and (CHS)33 (X).Treatment of VI with HI results, under elimination of benzene, almost quantitatively in the formation of I (XI), which is recristallized from THF as I*THF (1/1) (XIa).All attempts to obtain homogeneous products by reaction of VIII or X with HI, such as 3>I and (CHS)3(CH2CH2AsI2)3, failed.With H2O/NH3 or H2S/N(C2H5)3 XIa forms the cryptands 8(As4O4)6 (XII) or 8(As4O4)6 (XIII), which also can be considered as spherands.All the new compounds are characterized, as far as possible, by their IR, Raman, 1H NMR and mass spectra.
