The imidazolinone derivatives containing ferrocenyl moity(5a~5e) were synthesized by a tandem aza-Wittig reaction of 3 with phenyl isocynate and substituted phenols in yields of 57%~69%. The structures of title compounds were confirmed by elemental analysis,IR and 1H NMR. Two of them 5b and 5c exhibited fungicidal activities and none of them has herbicidal activity and insecticidal activity.展开更多
