Kuznetsov (Ref 3) used Na azidodithiocarbonate and its derivs to increase the sharpness of color tests for example, in neutral soln the anhyd Na salt gives a yel color in the presence of Cu. Hofman-Bang (Ref 6) found that dll solns of I, NaN, were catalyzed by Na azidodithiocarbonate and proposed a chain reaction mechanism. The Na salt is used primarily to prepare the heavy metal salts of azidodithiocarbonate, which are very sensitive expl compds Refs la)Beil 3, (86) [160] lb)F.Sommer, Ber 48, 1837-8(1915) CA 10, 342-3(1916)... 

The azidodithiocarbonates of the alkali and alkaline earth metals are all wh, deliq crystalline compds sol in w, ale, eth or acet and insol in CSj, CC14, chlf or benz. These salts usually contain w of hydration which makes them more stable than the anhyd heavy metal salts. However, they decomp slowly at RT and rapidly on heating. They have been prepd by three methods ... 

These studies have been extended by A. W. Browne and his coworkers,2"6 so that our knowledge of the chemistry of azidodithiocarbonic acid and the halogenoid azidocarbondisulphide is more complete than for most halogenoid compounds. The highly explosive character of the free halogenoid and of most of the anhydrous salts, particularly those of the heavy metals, makes them very dangerous and extremely difficult to handle.
