A herbicidal compound which is a Q-substituted 1-phenyl-4-substituted-1,4-dihydro-5H-tetrazol-5-one in which the Q-substituent is bonded to the ring-carbon atom at the 5-position of the phenyl group and in which: Q is --CH(R.sup.2)C(R.sup.3) (R.sup.4)Q' or --C(R.sup.2).dbd.C(R.sup.4)Q'; R.sup.2 and R.sup.3 are each, independently, hydrogen, alkyl, or halogen; R.sup.4 is hydrogen or lower alkyl; Q' is COOH, COOZ, COOR.sup.5, CON(R.sup.6) (R.sup.7), CN, CHO or C(O)R.sup.5 ; Z is a salt-forming cation; R.sup.5 is alkyl, cycloalkyl or aralkyl; each of R.sup.6 and R.sup.7 is, independently, hydrogen, alkyl, cycloalkyl, alkenyl, alkynyl, alkoxy, phenyl, benzyl or SO.sub.2 R.sup.8, or is one of said radicals substituted by halogen, alkyl or cyano, R.sup.8 being the same as R.sup.6 other than hydrogen or SO.sub.2 R.sup.8 ; said compound being one whose 5-Methoxy Analog and 5-Propargyloxy Analog are herbicides.
一种除草化合物,其为Q-取代的1-苯基-4-取代-1,4-二氢-5H-四唑-5-酮,其中Q取代基与苯基团的5位环碳原子键合,且其中:Q为--CH(R.sup.2)C(R.sup.3)(R.sup.4)Q'或--C(R.sup.2)=C(R.sup.4)Q';R.sup.2和R.sup.3各自独立地为氢、烷基或卤素;R.sup.4为氢或低烷基;Q'为COOH、COOZ、COOR.sup.5、CON(R.sup.6)(R.sup.7)、CN、CHO或C(O)R.sup.5;Z为盐形成阳离子;R.sup.5为烷基、环烷基或芳基烷基;R.sup.6和R.sup.7中的每一个独立地为氢、烷基、环烷基、烯基、炔基、烷氧基、苯基、苄基或SO.sub.2R.sup.8,或为卤素、烷基或氰基取代的上述基团之一,R.sup.8与R.sup.6相同,除了氢或SO.sub.2R.sup.8以外;该化合物为其5-甲氧基类似物和5-丙炔氧基类似物的除草剂。
