The present invention relates to a process for preparing fused tetrahydro-[
1
H]-triazoles of the formula I
1
where the variables R
a
, Z, Z
1
, X, W, n and Q are as defined in claim 1, by cyclization of compounds of the formula II
2
where R is C(X)OR
2
or C(X)SR
2
, where X is oxygen or sulfur, and R
2
is as defined in claim 1, in the presence of a base.
The invention also relates to compounds of the formula I where W is sulfur if Z is a methylene group optionally substituted by R
a
, and furthermore to compounds of the formula I where Q is a benzoxazole or benzothiazole radical, and to the use of these compounds as herbicides.
本发明涉及一种制备公式I的熔融四氢咪唑的方法,其中变量Ra、Z、Z1、X、W、n和Q如权利要求1中定义,通过在碱存在下,将公式II的化合物环化得到,其中R为C(X)OR2或C(X)SR2,其中X为氧或硫,R2如权利要求1中定义。该发明还涉及公式I的化合物,其中如果Z是可选地由Ra取代的亚甲基基团,则W为硫,此外还涉及公式I的化合物,其中Q为苯并噁唑或苯并噻唑基团,并将这些化合物用作除草剂。
