The invention relates to substituted quinoline herbicide intermediates of the formula
wherein W, X and Y are independently H, halogen, NO2, NH2 or -O-alkyl straight or branched C1-C6; Z is H, halogen, NO2, NH2, OH or -O-alkyl straight or branched C1-C6 and B is chlorine, bromine, a quaternary ammonium halide or -O-alkyl straight or branched C1-C6;
with the proviso that when the following values of B, W, X, and Y are taken simultaneously: B is -O-alkyl straight or branched C1-C6; W is H; X is H and Y is H, then Z is not OH or -O-alkyl straight or branched C1-C6.
Useful in the synthesis of the herbicides and methods for preparing 3-alkoxymethyl substituted quinoline herbicide intermediates.
本发明涉及式中的取代
喹啉除草剂中间体
其中 W、X 和 Y 独立地为 H、卤素、
NO2、NH2 或 -O- 烷基直链或支链 C1-C6;Z 为 H、卤素、 、NH2、OH 或 -O- 烷基直链或支链 C1-C6;B 为
