Abstract
Various 5H-pyrrolo(3',4':5,6)(1,4) dithiino-(2,3-C)(1,2,5)thiadiazole-5,7(6H)-diones corresponding to the formula ##STR1## wherein R represents --H, benzyl, phenethyl, a C.sub.1 -C.sub.10 straight or branched chain alkyl radical, a C.sub.3 -C.sub.10 cycloalkyl radical, a C.sub.1 -C.sub.10 straight or branched chain alkoxy radical, a C.sub.3 -C.sub.10 -cycloalkoxy, an ester of the formula --CH.sub.2 CH.sub.2 O--C(O)--R.sup.1, wherein R.sup.1 represents a C.sub.1 -C.sub.6 straight or branched chain alkyl radical or a C.sub.3 -C.sub.6 cycloalkyl radical or R represents phenyl substituted with from 0-5 halo, C.sub.1 -C.sub.6 straight or branched chain alkyl, cyano, nitro groups, or an ester of the formula --OC(O)--R.sup.1, wherein R.sup.1 represents a C.sub.1 -C.sub.6 straight or branched chain alkyl radical or a C.sub.3 -C.sub.6 cycloalkyl radical or an amide of the formula --C(O)--N(R.sup.2).sub.x, wherein each R.sup.2 independently represents a C.sub.1 -C.sub.6 straight or branched chain alkyl radical or a C.sub.3 -C.sub.6 cycloalkyl radical are disclosed. These compounds have been found to exhibit antimicrobial and marine antifouling activity in industrial and commercial applications and compositions containing these compounds are so employed.
