The present invention relates to novel trifluorobutenes of the formula (I)
1
wherein
R
1
represents hydrogen, halogen, or alkyl which may be unsubstituted or substituted with halogen, hydroxy, alkoxy, alkylthio, alkylcarbonyloxy, haloalkylcarbonyloxy or cyano, or represents alkylsulfonyloxy or represents phenyl which may be unsubstituted or substituted with halogen, alkyl, haloalkyl, alkoxy, alkylthio, alkylsulfonyl, haloalkoxy, haloalkylthio, phenyl, phenoxy, cyano or nitro.
R
2
represents hydrogen, halogen, or alkyl which may be unsubstituted or substituted with alkoxy or halogen, or represents alkoxycarbonyl, and
n represents
0, 1
or
2,
provided that if R
1
represents alkyl, R
2
does not represent halogen,
processes for their preparation and their use as nematicides.
本发明涉及一种新的三氟丁烯化合物,其化学式为(I)1,其中R1代表氢、卤素或烷基,烷基可以是未取代的或取代了卤素、羟基、烷氧基、烷硫基、烷羰氧基、卤代烷基羰基氧基或氰基;或者代表烷基磺酰氧基或苯基,苯基可以是未取代的或取代了卤素、烷基、卤代烷基、烷氧基、烷硫基、烷磺基、卤代烷氧基、卤代烷硫基、苯基、苯氧基、氰基或硝基。R2代表氢、卤素或烷基,烷基可以是未取代的或取代了烷氧基或卤素,或者代表烷氧羰基,n代表0、1或2。但是,如果R1代表烷基,则R2不代表卤素。本发明还涉及其制备方法以及作为杀线虫剂的用途。
