The structures of two azide containing imidazole derivatives are reported. Allylic azides are fairly reactive making them attractive starting compounds to convert into amides. The first, C 8 H 12 N 6 O 2 S, contains one azide group with an N α -N β distance of 1.229 (2) Å and an N β -N γ distance of 1.128 (2) Å. The second, C 8 H 11 N 9 O 2 S, contains two azide groups with an average N α -N β distance of 1.249 (2) Å and an average N β -N γ distance of 1.132 (2) Å. Each compound contains a bulky protecting group (di-methyl-amino-sulfon-yl) which can be easily removed under mildly acidic conditions.
