WebIn the Simmons–Smith reaction, it is a source of methylene. In fact the Simmons–Smith reaction does not produce free carbene but proceeds via Zn-CH 2 I intermediates. Diiodomethane is also a source of the equivalent of CH 2 2+. The synthesis of Fe 2 (CH 2)(CO) 8 illustrates this reactivity: Na 2 Fe 2 (CO) 8 + CH 2 I 2 → Fe 2 (CH 2)(CO) 8 ... WebOct 16, 2015 · CH 2 I – is formed rotationally excited. The partitioning between CH 2 I – vibration and HF + CH 2 I – relative translation energy depends on the treatment of CH 2 I – ZPE. Without a CH 2 I – ZPE constraint the energy partitioning is primarily to relative translation with little CH 2 I – vibration.
