“…Of note, the nitro group (20), iodide (21), bromide (24), silyl (25), tertiary amines (31,32), alkyne (37), olefins (38)(39)(40)(41), electron-rich heterocycles (33,42,43), and electron-deficient heterocycles (34)(35)(36) are all compatible with this transformation. Additionally, despite alcohols, acids, and amines, are known coupling partners with sulfonylhydrazones 28,29 , this transformation was competent for a range of acidic proton-containing substrates, such as phenol (22), anilines (23,28), unprotected indole (33), alkyl alcohol (26), carboxylic acid (27) and alkyl amines (29). Therefore, the relatively mild conditions and excellent chemoselectivity of this transformation enables access to products that would be either difficult or impossible to prepare via other known methodologies, including organolithium-promoted 1,2-metallate rearrangement and transition-metal catalysis (one-or twoelectron) 30 .…”
