The reaction of 2-ethoxy-1,3-dithiolane with carbonyl compounds such as aldehydes and ketones was investigated. The reaction proceeded smoothly in the presence of the HgCl2-catalyst to afford 2-substituted and 2,2-disubstituted 1,3-dithiolanes. The reaction also offers an interesting alternative to the previously reported methods of synthesizing 1,3-dithiolanes which involve the acid-catalyzed reaction of carbonyl compounds with 1,2-ethanedithiol.
研究了2-乙氧基-1,3-二硫烷与醛和酮等羰基化合物的反应。在HgCl2催化剂的存在下,反应顺利进行,得到2-取代和2,2-双取代的1,3-二硫烷。该反应还为合成1,3-二硫烷提供了一种有趣的替代方案,与先前报道的羰基化合物与1,2-乙二硫醇的酸催化反应方法相比。
