The addition of cesiumfluoroxysulfate (1) to a variety of alkenes (1-hexene, styrene, E-stilbene, cyclohexene, diene 14) proceeds under mild conditions giving the previously unknown vicinal fluoro alkyl sulfates. The structures of these products were rigorously established by thorough 1H, 19F and 13C NMR data analyses. The studied reactions exhibit low regio- and stereo- selectivities with a preference
在温和的条件下,向各种烯烃(1-己烯,苯乙烯,E-苯乙烯,环己烯,二烯14)中添加氟代硫酸铯(1),得到先前未知的邻位氟代烷基硫酸盐。通过彻底的1 H,19 F和13 C NMR数据分析,严格确定了这些产物的结构。所研究的反应表现出低的区域选择性和立体选择性,并且优先选择抗马尔可夫尼可夫和顺式加成。顺式产物形成的优势与添加的一致机制是一致的。
