摘要

The present invention provides a fluoropropene compound represented by Formula I: wherein R<1> represents various organic groups defined in the description; Z represents an oxygen atom, a sulfur atom or NR<17> in which R<17> represents a hydrogen atom or a C1-C3 alkyl group; R<2>, R<3> and R<4> independently represent a C1-C3 alkyl group, a C1-C3 haloalkyl group, a halogen atom or a hydrogen atom, provided that R<2>, R<3> and R<4> do not simultaneously represent a hydrogen atom; r represents an integer of 0 to 2; and X represents a halogen atom. These compounds are endowed with insecticidal activity. Intermediate compounds for the preparation of the above compounds are also provided.
