react quantitatively with S2NAsF6via a concerted symmetry allowed cycloaddition to give 1 : 1 and 2 : 1 stoicheiometric cationic products: the generality of reaction is rationalised and the X-ray crystal structure determination of the 1,4-dithia-7-azanorbornylium cation is reported.
许多烯烃通过协调一致的对称性与S 2 NAsF 6定量反应,允许环加成反应生成
化学计量比为1:1和2:1的阳离子产物:合理化了反应的一般性,并通过X射线晶体结构确定了1,4-据报道有dithia-7-azanorbornylium阳离子。
