Abstract

The combination of 6-SIDipp·AlH₃ (1) and 5-IDipp resulted in the ring expansion of 6-NHC, while the five-membered NHC remained unchanged, which was subsequently explained by DFT studies. Besides, the substitution chemistry of 1 was also studied with TMSOTf and I₂, which gave rise to the substitution of a hydride by triflate or iodide ligands.
