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.
CON 3 --> RÃ¯¿½NHÃ¯¿½CO 2 C 2 H 5 - R.NH2 azide urethane The secondary amines are prepared, together with the primary and tertiary, by the action of ammonia on the alkyl iodides (see below), or by the hydrolysis of para-nitroso derivatives ` of tertiary aromatic amines, such as para-nitrosodimethylaniline, thus: NOÃ¯¿½C 6 H 4 Ã¯¿½N(CH 3) 2 Ã¯¿½ H 2 O = NOÃ¯¿½C 6 H 4.
