The present invention relates to a method for producing 1-hydroxymethyl-1,2-diphenyloxiranes from 2,3-diphenylpropenals by means of epoxidation and reduction. The formation of objectionable by-products can be suppressed in that the reduction is started before the 2,3-5 diphenylpropenal is completely converted. The hydroxymethyl diphenyloxiranes represent valuable intermediate products for producing 1-azolylmethyl-1,2-diphenyloxiranes, wherein the latter can be easily produced from said intermediate products by introducing the azolyl group.
本发明涉及一种通过环氧化和还原从2,3-二苯基
丙烯醛制备1-羟甲基-1,2-二苯基环氧烷的方法。通过在2,3-二苯基
丙烯醛完全转化之前开始还原,可以抑制令人不快的副产物的形成。羟甲基二苯基环氧烷是制备1-氮杂基甲基-1,2-二苯基环氧烷的有价值的中间产物,后者可以通过引入氮杂基团从上述中间产物中轻松制备。
