Abstract
Abstract 5-Nitrothiazoles substituted in the 2-position by a heteroaromatic thio group are useful as plant fungicides and have activity against various fungi pathogenic to animals such as Candida and dermatophytes. The compounds are prepared by condensation of a 2-halo-5-nitrothiazole with a salt of the appropriate mercapto substituted heteroaromatic compound.
