Primary and tertiary nitronate ions and sulphonyl bromides and iodides rapidly equilibrate with the nitrohalides and sulphinate ion. Products are determined by solvent and by the occurrence of cross-equilibrium reactions, some of which have single-electron-transfer mechanisms. The reaction of arene-sulphinate and -thiolate ions with 1,2-dibromo-2-nitro-1-phenylethane gave E-β-nitrostyrene by Z-philic

A microbicidal/microbistatic composition for industrial use which contains 4,5-dichloro-1,2-dithiol-3-one and bromonitrostyrene and a method of killing or inhibiting the growth of microorganisms or controlling slime formation using the composition.
An aqueous isothiazolone formulation useful for antiseptic or antifungal treatment of various synthetic polymeric emulsions, which comprises (a) a specific isothiazolone compound, (b) water or an aqueous solvent and (c) a specific nitrobromo or cyanobromo compound.
The use of novel compositions for preserving aqueous systems normally subject to spoilage is disclosed. The compositions incorporate an antimicrobial agent into an inert and biodegradable carrier. The resulting compositions are stable, active, non-toxic, non-corrosive, biodegradable, compatible with ecosystems while having a flash point above 200°F (93°C) and a pleasant odor.
