Novel substituted nitroguanidine derivatives and salts thereof having the following formula:
wherein R¹ is a substituted or unsubstituted heterocyclic group; R² is a group attached through a sulfur atom, a group attached through a phosphorus atom, cyano, -CO-OR⁶ wherein R⁶ is a substituted or unsubstituted hydrocarbon group or a substituted or unsubstituted heterocyclic group, or -CO-NR⁷R⁸ wherein R⁷ and R⁸, which are the same or different, are each independently hydrogen, a substituted or unsubstituted hydrocarbon group or a substituted or unsubstituted heterocyclic group, or R⁷ and R⁸, taken together with the nitrogen atom to which they are attached are a cyclic amino group; R³ is hydrogen, a substituted or unsubstituted hydrocarbon group (except for one substituted with an oxo group at the binding site), a group attached through a sulfur atom, a group attached through a phosphorus atom, cyano, -CO-R⁹ wherein R⁹ is hydrogen, a substituted or unsubstituted hydrocarbon group or a substituted or unsubstituted heterocyclic group, -CO-OR¹⁰ wherein R¹⁰ is a substituted or unsubstituted hydrocarbon group or a substituted or unsubstituted heterocyclic group, or -CO-NR¹¹R¹² wherein R¹¹ and R¹², which are the same or different, are each independently hydrogen, a substituted or unsubstituted hydrocarbon group or a substituted or unsubstituted heterocyclic group, or R¹¹ and R¹², taken together with the nitrogen atom to which they are attached are a cyclic amino group; and R⁴ is hydrogen or a lower alkyl group; which have unexpectedly potent pesticidal activity and very low toxicity.
