Abstract
The N-alkylation of 2-nitroimidazole through its 'naked' anion, formed from its alkali metal salts in the presence of crown ethers and in homogeneous solution, is shown to be a useful preparative procedure. The reactions of α,ω-dihaloalkanes can be controlled to afford either the mono- or diheteroarylalkane. The procedure has been used to alkylate theophylline and to prepare a compound of use as a probe to identify, locate and quantify hypoxia in sections from solid tumours.
