摘要

2-Pyrimidinylmethyl- and 2-triazinylmethyl-benzoic and nicotinic acid derivs. (I) and their alkali metal, alkaline earth metal and ammonium salts are new. In (I) R1 = H; 1-12C alkyl opt. substd. by hydroxy, halogen, 1-4C alkoxy, 1-4C alkylthio, 3-6C cycloalkyl, benzyl, furyl, tetrahydrofuryl, phenyl, halophenyl, 1-4C alkylphenyl, 1-4C alkoxyphenyl, nitrophenyl, cyano, carboxy, 1-4C alkoxycarbonyl, 1-4C alkylamino, di-1-4C alkylamino, tri-1-4C alkylammonium halide, 2-5C alkyleneimino, or di-1-4C alkylmethyleneimino; 2-12C alkyl interrupted by O or S atom(s); 2-12C alkyl interrupted by O or S atom(s) and substd. by hydroxy, halogen, 1-4C alkoxy, 1-4C alkylthio, 3-6C cycloalkyl, benzyl, furyl, tetrahydrofuryl, phenyl, halophenyl, 1-4C alkylphenyl, 1-4C alkoxyphenyl, nitrophenyl, cyano, carboxy, 1-4C alkoxycarbonyl, 1-4C alkylamino or di-1-4C alkylamino; 3-8C alkenyl or 3-8C alkynyl opt. substd. by 1-3C alkoxy, phenyl or halogen; 3-6C cycloalkyl opt. substd. by methyl; di-1-4C alkylmethyleneimino; or 3-6C cycloalkyleneimino; R2, R3 = halogen, 1-4C alkyl opt. substd. by halogen or 1-4C alkoxy, 1-4C alkoxy, 1-4C alkylthio, 1-4C alkylamino or di-1-4C alkylamino; R4, R5 = H, halogen, nitro, cyano, 1-4C alkyl opt. substd. by halogen, 1-4C alkoxy, phenoxy or 1-4C alkoxycarbonyl; R6 = H, halogen or 1-4C alkyl; X, Y = CH or N. USE/ADVANTAGE - Cpds. (I) are herbicides, fungicides and plant growth regulators. Herbicidal use is esp. as defoliants, desiccants, and weedkillers, e.g. in amt.s of 0.001-5 kg/ha.
