Two secondary amides (N-methylacetamide and 2-pyrrolidinone) were used as additives with SmI2 in THF to estimate the extent of N–H bond weakening upon coordination. Mechanistic and synthetic studies demonstrate significant bond-weakening, providing a reagent system capable of reducing a range of substrates through formal hydrogen atom transfer.
两种仲酰胺(N-甲基乙酰胺和2-吡咯烷酮)与SmI 2在THF中的添加剂一起使用,以评估配位时N–H键减弱的程度。机械和合成研究表明,键的弱化作用显着,它提供了一种试剂系统,能够通过正式的氢原子转移来减少一系列底物。
