The invention relates to a fluorine-containing olefin compounds and nitrogen heterocyclic and its preparation and use. The olefin compounds of the formula I is a compound represented by, or isomer thereof or in agricultural pharmacy acceptable salt. The compounds of formula I shown by accompanies two fluorine alkene hydrocarbon compound containing an aromatic ring with the nitrogen-containing heterocyclic (NH-containing) compound reaction. The present invention provides olefin compounds as crops fungicide application. In formula I, R1 - R4 Are independently selected from the group: hydrogen, C1 - C3 Alkyl, C1 - C3 Alkoxy, halogen in a; or R1 - R4 In any two adjacent combined is divalent phenyl or divalent oxygen surcharge or six-membered heterocyclic ring of the heterocyclic radical, the rest is H; A is nitrogen-containing five-membered or six-membered heterocyclic, substituted by thienyl N-containing five-membered or six-membered heterocyclic, or by phenyl substituted N or benzo-containing five-membered or six-membered heterocyclic; said heterocyclic hetero atom number is 1 - 3.

A mild and versatile method for the construction of C-N bonds by the reaction of (2,2-difluorovinyl)arenes with various N-H-containing heterocycles in the presence of K3PO4 has been developed. The reaction proceeded efficiently at room temperature (25 °C) affording the (E)-N-α-fluorovinyl derivatives of azoles 3 in good to excellent yields with relatively high stereoselectivity.
