Active substructures combination is widely used in the new pesticide research. In our research, the substructures such as urethane group, guanidyl, ferrocenyl and ketoimine were used as basic structure units, and urethane group were respectively combined with guanidyl, ferrocenyl and ketoimine to form guanidoethyl N-arylcarbamate hydrochlorides (1) and ferrocenylethanone imino N-arylcarbamates (2), and 35 new compounds that had never been reported were synthesized (their structures as show in Fig.1). The st...
