Compounds having the structure: ##SPC1## Wherein R.sup.1 and R.sup.2, alike or different, are alkyls of 2 to 7 carbon atoms in which there are no more than 3 carbon atoms in a line from the aromatic ring; R.sup.3 is an alkyl of 1 to 3 carbon atoms; n is 0, 1 or 2; and X is F, Cl, Br, I, or CN; with the provisos that 1. R.sup.1 and R.sup.2 are not ortho to each other, 2. at least one of R.sup.1 and R.sup.2 contains at least 3 carbon atoms, and 3. X is not ortho to the ##EQU1## have been found to be selective herbicides.
具有以下结构的化合物: ##SPC1## 其中R.sup.1和R.sup.2,无论相同或不同,都是2到7个碳原子的烷基,其中从芳香环到最多有3个碳原子; R.sup.3是1到3个碳原子的烷基; n为0、1或2; X为F、Cl、Br、I或CN; 但须符合以下条件:1. R.sup.1和R.sup.2不是对位的; 2. 至少R.sup.1和R.sup.2中的一个含有至少3个碳原子; 3. X不是对位于##EQU1## 的。已发现这类化合物是选择性除草剂。
