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.
本发明涉及一种制备一般式I的1-三唑基乙基醚衍生物的方法,其中定义在权利要求1中,该方法包括:(a)在存在酸催化剂或酸缩合剂的情况下,将式II的环氧化物在-20℃至+100℃的温度下与式III R.sub.3 --OH (III)的醇反应,得到式IV的乙二醇单醚;(b)随后,在存在酸中和剂或缩合剂的情况下,将式IV的乙二醇单醚或其酯之一,在0℃至150℃的温度下与式V的三唑反应,其中公式II至IV中的取代基R.sub.1、R.sub.2和R.sub.3如公式I中所定义,公式V中的M为氢或金属原子。本发明还描述了公式I范围内的新化合物及其用途。
