Title compds. (I; R1=H, CN, C1-4 alkyl, alkenyl, alkynyl; R2=halogen; R3, R4=F, Cl, Br, CH3; R5=H, halogen, CH3, CH3O-; R6=H, CN, Halogen, NO2, NH2, substituted halogen C1-4 alkyl) used as inseticides, were prepd. by the reaction of II and III with aq. acid or catalyst. In an example, 5.57g X and 3.67g XI was added dropwisely with stirring to the mixt. of 1.13g NaCN 1.77cc water 100cc n=C6H14 and 0.6g (C4N9)4N+Br- at 20-25≰C for 4hr. The reactant was extracted by the mixt. of toluene and water. Organic layer was dried (MgSO4) and the solvent removed under reduced press. to give 7g (I).
