oligomers, previously unreported reactivity of the N-substituted disulfonimide functional group was discovered. Under basic conditions, unexpected lengthening of the oligomers occurs through a "transdisulfonimidation" reaction, whereby new disulfonimides are synthesized from existing ones by reaction with sulfonamide anion. This process appears to proceed via formation of a sulfene intermediate. Support for
首次合成烷基二磺酰亚胺低聚物。在合成这些低聚物的过程中,发现了以前未报道的 N-取代二磺酰亚胺官能团的反应性。在碱性条件下,低聚物通过“转二磺酰亚胺化”反应发生意外延长,由此通过与磺酰胺阴离子反应从现有二磺酰亚胺合成新的二磺酰亚胺。该过程似乎是通过形成亚砜中间体来进行的。对 E1cB(Rev) 机制的支持包括同位素加扰、取代基效应和亚砜捕获。
