Crystal structures of 4-{(E)-3-[(imino-λ5-azanylidene)amino]prop-1-enyl}-N,N-dimethylimidazole-1-sulfonamide and 2-[(imino-λ5-azanylidene)amino]-4-{(E)-3-[(imino-λ5-azanylidene)amino]prop-1-enyl}-N,N-dimethylimidazole-1-sulfonamide

Abstract

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, C8H12N6O2S, contains one azide group with an Nα—Nβ distance of 1.229 (2) Å and an Nβ—Nγ distance of 1.128 (2) Å. The second, C8H11N9O2S, contains two azide groups with an average Nα—Nβ distance of 1.249 (2) Å and an average Nβ—Nγ distance of 1.132 (2) Å. Each compound contains a bulky protecting group (dimethylaminosulfonyl) which can be easily removed under mildly acidic conditions.
