Summary "Alkynyl-phenyl-substituted cyclic dione compounds and derivatives thereof with herbicidal activity" The present invention relates to a compound of the formula (i): wherein: x is methyl or chlorine； R1 is fluorine or bromine； R2 is ethynyl, C1-3 alkoxy, C1-3 haloalkoxy, or C1-3 alkoxy-C1-3 alkoxy-； eq is a pyran-3,5-dione-4-yl, a thiopyran-3,5-dione-4-yl, a piperidin-3,5-dione-4-yl, a cyclopentane-1,3-dione- 2-yl, a cyclohexane-1,3,5-trione-2-yl, a cyclohexane-1,3-dione-2-yl, or a cycloheptane-1,3-dione-2-yl, or a derivative thereof (e.g., a fused derivative such as a fused bicyclic derivative, and / or a spirocyclic derivative), or an enol ketone tautomer derivative thereof, wherein q is further defined herein； and wherein the compound of formula (i) is optionally present as an agrochemical acceptable salt thereof. preferably x is methyl； and / or R1 is fluorine； and / or r2 is -o-r2a, where r2a is methyl, ethyl, trifluoromethyl, difluoromethyl, trifluoroethyl, or -ch2ch2och3. These compounds are suitable for use as herbicides. Accordingly, the invention also relates to a method of controlling weeds, in particular monocotyledonous grass weeds, in useful plant crops comprising applying a compound of formula (I), or a herbicidal composition. comprising such a compound, weeds and / or plants and / or their location.resumo "compostos de dionas cíclicas substituídas com alquinil-fenil e seus derivados com atividade herbicida" a presente invenção refere-se a um composto da fórmula (i): (i) em que: x é metil ou cloro； r1 é flúor ou bromo； r2 é etinil, alcoxi c1-c3, haloalcoxi c1-c3, ou alcoxi(c1-c3)-alcoxi(c1-c3)-； e q é um piran-3,5-diona-4-il, um tiopiran-3,5-diona-4-il, um piperidina-3,5-diona-4-il, um ciclopentano-1,3-diona-2-il, um cicloexano-1,3,5-triona-2-il, um cicloexano-1,3-diona-2-il, ou um cicloeptano-1,3-diona-2-il, ou um derivado destes (por exemplo, um derivado fundido tal como um derivado bicíclico fundido, e/ou um derivado espirocíclico), ou um de
