Abstract
Abstract Compounds of the formula ##STR1## wherein X is cyano or ##STR2## Q is Cl, --OR 1 , --SR 1 or --NR 2 R 3 ; R 1 is hydrogen or alkyl of 1-2 carbon atoms, R 2 is hydrogen or methyl; and R 3 is hydrogen, alkyl of 1-4 carbon atoms or phenyl, With the proviso that (a) when R 2 is hydrogen, R 3 is hydrogen or alkyl of 1-3 carbon atoms or phenyl and (b) when Q is --SR 1 , R 1 is not hydrogen, are useful as fungicides and reaction intermediates. These compounds may be prepared by reacting substituted 3,4-dimercaptoisothiazole salts with sulfur monochloride.
