The present invention provides a method for producing an unsaturated ether compound represented by general formula (2) below, the method comprising reacting an acetal represented by general formula (1) below in the presence of an aliphatic or aromatic sulfonic acid and an organic base having a total carbon number of 3 to 7. (In the formulae, R1, R2, and R3 may be the same or different and each represent substituted or unsubstituted alkyl, substituted or unsubstituted aryl, or substituted or unsubstituted aralkyl, or R1 and R2 form cycloalkyl together with the adjacent carbon atom.)
本发明提供了一种生产下式(2)所代表的不饱和醚化合物的方法,该方法包括使下式(1)所代表的缩醛在脂肪族或芳香族磺酸和总碳数为3至7的有机碱存在下进行反应。(式中,R1、R2 和 R3 可以相同或不同,各自代表取代或未取代的烷基、取代或未取代的芳基、取代或未取代的芳烷基,或 R1 和 R2 与相邻碳原子一起形成环烷基)。
