The present application relates to novel guanidine derivatives of the formula (I)
in which
R1 represents a five- or six-membered heterocyclic group;
R2 represents hydrogen or alkyl,
R3 represents the groupings —OR4, —OCOR5, —OCOOR6, —OCONR7R8 and —OSO2R9, where
R4, R5 and R6 independently of one another represent alkyl, alkoxyalkyl, halogenoalkyl, alkenyl, alkinyl, alkylaminoalkyl, dialkylaminoalkyl, optionally substituted cycloalkyl and in each case optionally substituted phenyl or benzyl,
R7 and R8 independently of one another represent hydrogen, alkyl, alkenyl and in each case optionally substituted phenyl or benzyl and
R9 represents alkyl or optionally substituted phenyl,
A represents the groupings —CH2CH2—, (CH2)3 and —CH═CH— and
z represents cyano or nitro,
with the proviso that, if Z represents NO2 and A represents —CH2CH2—, the radical R2 represents hydrogen; and the compound of the formula (I) in which
R1
R2 H,
R3 OCH3,
A —CH2CH2— and
Z NO2 is excluded.
The compounds serve for controlling insects, arachnids and nematodes.
本申请涉及公式(I)的新型胍基衍生物,
其中R1代表五元或六元杂环基;
R2代表氢或烷基,
R3代表基团—OR4,—OCOR5,—OCOOR6,—OCONR7R8和—OSO2R9,
其中R4、R5和R6分别独立地代表烷基、烷氧基烷基、卤代烷基、烯基、炔基、烷基氨基烷基、二烷基氨基烷基、可选取代的环烷基和各自可选取代的苯基或苄基,
R7和R8各自独立地代表氢、烷基、烯基和各自可选取代的苯基或苄基,
R9代表烷基或可选取代的苯基,
A代表基团—CH2CH2—,(CH2)3和—CH═CH—,
z代表氰基或硝基,
但如果Z代表NO2且A代表—CH2CH2—,则基团R2代表氢;并且公式(I)中R1R2 H,R3 OCH3,A—CH2CH2—和Z NO2的化合物被排除。
这些化合物用于控制昆虫、蜘蛛和线虫。
