“…Uncouplers of oxidative phosphorylation are generally associated with a broad spectrum of biocidal activity. This is certainly true of the polychloro-2-trifluoromethylbenzimidazoles [107,727,729,734,737,738,[753][754][755][756][757][758]. Derivatives of these compounds with substituents (alkyl [753,759,760], C0 2 R [733,753,[761][762][763][764][765], S02R [766,767], CONHR [768], CSNR 2 [769], OR [769a]) on the ring nitrogen atom or with substituents (alkyl [770], aryl [771], C2 F 5 [753, 754, 756, 769a] , CF 2 Cl [772], CC13 [770,773], SH [770], SMe [770], S02Me [770], C0 2 Et [770]) other than a trifluoromethyl group in the 2-position are also of interest in this respect.…”
