Nuevas 3-fenilpirrolidina-2,4-dionas sustituidas con alquinilo y su uso como herbicidas La presente invención se refiere a nuevas 3-fenilpirrolidina-2,4-dionas sustituidas con alquinilo de acuerdo a la fórmula general (I) o sus sales aceptables agroquímicamente,en la que X = C1-C4-alquilo, C1-C4-haloalquilo o C3-C6-cicloalquilo, Y = C1-C4-alquilo o C3-C6-cicloalquilo, R1 = hidrógeno, C1-C6-alquilo, o C3-C6-cicloalquilo, R2 = hidrógeno o metilo, R3 = C1-C6-alquilo o C1-C6-alcoxi-C2-C6-alquilo, G = hidrógeno, un grupo saliente L o un catión E, donde R3 no es igual a metilo, si R1 = metilo y R3 no es igual a C1-C3-alquilo, si R1 = H. The present invention relates to novel effective alkynyl-substituted N-phenylpyrrolidine-2,4-diones according to the general formula (I) or agrochemically acceptable salts thereof,whereX=C1-C4-alkyl, C1-C4-haloalkyl or C3-C6-cycloalkyl, Y=C1-C4-alkyl or C3-C6-cycloalkyl, R1=hydrogen, C1-C6-alkyl, or C3-C6-cycloalkyl, R2=hydrogen or methyl, R3=C1-C6-alkyl or C1-C6-alkoxy-C2-C6-alkyl, G=hydrogen, a cleavable group L or a cation E.The invention further relates to a herbicidal composition comprising a compound of the general formula (I) and to the use of the compounds according to the invention for controlling weeds and weed grasses in crops of useful plants.
