Chlorine azide, C1 N 31 was discovered by F.
This compound is then decomposed by ammonia, dinitrophenylhydrazoate being formed, which on hydrolysis with alcoholic potash gives potassium hydrazoate (azide) and dinitrophenol.
Raschig (Be y ., 1908, 4 1, p. 4 1 94) as a highly explosive colourless gas on acidifying a mixture of sodium azide and hypochlorite with acetic or boric acid.
The use of a secondary azide was successful, although the stereoselectivity of the reduction of the resultant iminium ion was low.
The buffer solution contains harmless concentrations of sodium azide.
