Essentially, a process is described for the preparation of the 1-triazolylethyl ether derivatives, defined in claim 1, of the general formula I ##STR1## which consists in (a) reacting an oxirane of the formula II ##STR2## at temperatures of -20.degree. to +100.degree. C., in the presence of an acid catalyst or an acid condensation agent, with an alcohol of the formula III R.sub.3 --OH (III) to give a glycol monoether of the formula IV ##STR3## and (b) subsequently reacting the glycol monoether of the formula IV or one of its esters, in the presence of an acid-binding agent or condensation agent, at temperatures of 0.degree. to 150.degree. C., with a triazole of the formula V ##STR4## the substituents R.sub.1, R.sub.2 ; amd R.sub.3 in the formula II to IV being as defined under formula I and M in formula V being hydrogen or a metal atom. The novel compounds within the scope of formula I and their use are also described.
本质上,描述了一种用于制备一般式I的1-三唑基乙醚衍生物的过程,该一般式I定义如权利要求1中所述,该过程包括(a)在-20摄氏度至+100摄氏度的温度下,存在酸催化剂或酸缩合剂的情况下,将一种一般式II的环氧丙烷与一种一般式III的醇R3-OH(III)反应,得到一种一般式IV的乙二醇单醚;以及(b)随后,在0摄氏度至150摄氏度的温度下,存在酸中和剂或缩合剂的情况下,将一种一般式IV的乙二醇单醚或其酯之一与一种一般式V的三唑反应,其中在一般式II至IV中的取代基R1、R2和R3如在一般式I下所定义,一般式V中的M为氢或金属原子。还描述了在一般式I范围内的新化合物及其用途。
