  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。

  The regioselectivity of the reactions of 1,3-dilithioalk-1-ynes with various electrophiles has been examined. With formaldehyde and cyclic ketones, reactions occur both at C-1 and C-3 to give alk-2-yne-1,5-diols. In contrast reactions with carbon dioxide give allene-1,3-dicarboxylic acids.

  已经研究了1，3-二硫代硫基-1-炔与各种亲电试剂反应的区域选择性。与甲醛和环状酮一起，反应在C-1和C-3处进行，生成alk-2-yne-1,5-二醇。相反，与二氧化碳的反应产生了1，3-二烯丙基丙二酸。
