5(6)-Benzene ring substituted benzimidazole-2-carbamate derivatives having anthelmintic activity

Abstract

Carbalkoxythioureidobenzene derivatives represented by the following formula: ##STR1## where R is a lower alkyl group having 1 to 4 carbon atoms; R.sup.1 is --SR.sup.2, --SOR.sup.2, --SO.sub.2 R.sup.2, --OR.sup.2, --SCN, --SC(O)NR.sup.3 R.sup.4, or --M'(CH.sub.2).sub.n MR.sup.7 where n is 1-4; R.sup.2 is lower alkyl having 1 to 6 carbon atoms, cycloalkyl having 3 to 7 carbon atoms, lower alkenyl or lower alkynyl having 3 to 6 carbon atoms, aralkyl or aryl, provided that when R.sup.1 is --SO.sub.2 R.sup.2, R.sup.2 is not aralkyl or phenyl; R.sup.3 and R.sup.4 are independently hydrogen or lower alkyl having 1 to 6 carbon atoms; Y is amino, nitro, acylamino where the acyl portion has 1 to 6 carbon atoms, --NHC(O) (CH.sub.2).sub.m COOH where m is 1-6, or --NHC(S)NHCOOR; M and M' are independently O, S or ##STR2## and R.sup.7 is lower alkyl having 1 to 4 carbon atoms or aryl. The R.sup.1 substitution is either at the 4- or 5-position. The compounds are useful as pesticides, particularly as anthelmintic and antifungal agents.
