Sulfanuric Chloride—Cyclic Trimer

The use of azide reagents is also important for the synthesis of cyclic sulfur(VI)-nitrogen systems. The reaction of SOCI2 with sodium azide in acetonitrile at -35°C provides a convenient preparation of the trimeric sulfanuric chloride [NS(0)C1]3 (Eq. 2.16). " Thionyl azide, SO(N3)2 is generated by the heterogeneous reaction of thionyl chloride vapour with silver azide (Eq. 2.17). This thermally unstable gas was characterized in situ by photoelectron spectroscopy. The phenyl derivative of the six-membered ring [NS(0)Ph]3 can be prepared from lithium azide and PhS(0)Cl. ... [Pg.23]

The cyclic sulfanuric chlorides, (NS0C1) , are of interest because they are isoelectronic with the cyclic phosphonitrilic chlorides, (NPCl2)n- Although the formation of a variety of substances with n = 3 or more appears reasonable, only the cyclic trimers have been isolated.1 At least three, apparently conformational, isomers of composition (NSOCl)3 have been... [Pg.10]
