The present invention is to provide 2,3-dihalogeno-6-trifluoromethylbenzene derivatives represented by a general formula [I];
wherein X1 and X2 are the same or different and each independently represents fluoro or chloro; Y represents COOH, CONH2, CN, CHO, CH=NOH or COOR', wherein R' is C1-C4 alkyl, except the case that X1 and X2 are each chloro and Y is COOH, which are useful as the starting materials for producing pesticides, drugs and the like, and a process for producing such derivatives.
本发明旨在提供通式[I]代表的 2,3-二卤代-6-三氟甲基苯衍生物;
其中X1和X2相同或不同,且各自独立地代表氟或氯;Y代表COOH、CONH2、CN、CHO、CH=NOH或COOR',其中R'为C1-C4烷基,但X1和X2各自为氯且Y为COOH的情况除外,这些衍生物可用作生产农药、药物等的起始原料,以及生产此类衍生物的工艺。
