ANILINE DERIVATIVE, ITS PREPARATION, FUNGICIDE FOR AGRICULTURAL AND HORTICULTURAL PURPOSES CONTAINING THE SAME

摘要

NEW MATERIAL:A compound of formula I (X, Y are lower alkylene, lower alkoxyalkylene; k, l, m, n are 0, 1; R1 is lower alkyl, lower alkoxyl, H; Z is H, lower alkyl, lower alkenyl; A is O, S; B is lower alkyl, phenyl, lower alkenyl). EXAMPLE:Isopropyl N-(8-chloro-1,3-benzodioxan-6-yl)carbamate. USE:Fungicide for agricultural and horticultural purposes: it shows strong fungicidal effect selectively against strains resistant to benzimidazole thiofanate fungicides. It is also used to control strains resistant to chemicals. PREPARATION:The reaction of a compound of formula II with another compound of formula III (R5 is halogen) is carried out in an organic solvent such as benzene, using an acid acceptor such as pyridine, when necessary, in the presence of a phase transfer catalyst to give the objective compound of formula I .
