Dehydrofluorination of bis(1,1-dihydropolyfluoroalkyl) sulfides with lithium hydroxide in morpholine occurs in a controlled manner with the formation of a new type of bis(enamine) sulfides, bis[2-(morpholin-4-yl)polyfluoroalk-1-en-1-yl]sulfanes, hydrolysis and subsequent fluorination of which leads to the production of novel fluorine-containing 1,4-oxathiine derivatives with divalent sulfur.

合成在位置2和6上具有多氟烷基取代基的新型1,4-氧代嘧啶衍生物

在吗啉中用氢氧化锂对双（1,1-二氢多氟烷基）硫化物进行脱氟化氢反应，并以可控的方式发生，形成了新型的双（烯胺）硫化物，即双[2-（吗啉-4-基）聚氟烷基-1-烯基-1,4-亚砜]的水解和随后的氟化反应导致生成具有二价硫的新型含氟1,4-氧代嘧啶衍生物。
