Sulfoxonium ylides 3a-h were synthesized by silylation of the cyclic methylene disulfones 1,3-dithietane 1,1,3,3-tetraoxide (1) and 1,3,5-trithiane 1,1,3,3,5,5-hexaoxide (4) with the silylating agents silyl nonafluorobutanesulfonates. The structure and constitution of the ylides were established with 1H-NMR, 13C-NMR, 29Si-NMR spectroscopy, mass spectrometry, and elemental analysis. On the route to
通过环亚甲基二砜1,3-二硫杂环丁烷1,1,3,3-四氧化物(1)和1,3,5-三噻烷1,1,3,3,5,5的甲硅烷基化反应合成亚砜ox 3a-h -六氧化物(4)与甲硅烷基化的九氟丁基磺酸盐。用1 H-NMR,13 C-NMR,29 Si-NMR光谱,质谱和元素分析确定酰基化物的结构和组成。到氧化锍路线叶立德一类新的不饱和disulfenes的7,8,12,13的1和4中通过Knoevenagel反应和取代反应来合成。新形成的烷基二硫的阴离子制备16a,b,e,f和三价阴离子17,并通过1 H-NMR和13 C-NMR光谱进行表征,并与酰化物的结果进行比较。
