and conformation are examined by 1H NMR, and to the sulfone whose X-ray structure is determined. 2-Benzylidene-1,3-oxathiolane is also prepared and the behavior of the three S-oxidized oxathiolane derivatives upon FVP is examined. While extrusion of SOn to give ethene and a carbonyl compound predominates in all three cases, the sulfoxide gives also bis(2-hydroxyethyl) disulfide, most likely formed via
摘要 2-亚苄基-1,3-二氧戊环异构化为 3-苯基丁内酯在快速真空热解 (FVP) 条件下很容易发生。2-二苯基甲基-1,3-oxathiolane 和 2-benzyl-1,3-oxathiolane 已被制备,后一种化合物已被氧化为相应的亚砜,其结构和构象通过 1H NMR 进行检测,并氧化为砜,其 X -射线结构确定。还制备了 2-Benzylidene-1,3-oxathiolane,并检查了三种 S-氧化 oxathiolane 衍生物对 FVP 的行为。虽然在所有三种情况下挤出 SOn 以产生乙烯和羰基化合物,但亚砜也产生双(2-羟乙基)二硫化物,最有可能通过硫杂硫醚 S-氧化物和 1,2-氧杂硫杂环丁烷形成。图形概要
