摘要：
A series of novel 2-fluoro and 2-trifluoromethyl-6-substituted anilines were prepared in a regiospecific manner and reacted with substituted 1,2,4-triazolo[1,5a]pyrimidine-2-sulfonyl chlorides to prepare the title compounds which were evaluated as potential herbicides. Heteroatom directed ortho-lithiation was used to prepare the key aniline intermediates. Details of the synthesis, biological properties and a brief discussion of the structure-activity relationship are presented.
