Silver-Promoted Synthesis of Vinyl Sulfones from Vinyl Bromides and Sulfonyl Hydrazides in Water
2020
The synthesis of vinyl sulfones via silver-promoted cross-coupling of vinyl bromides with sulfonyl hydrazides was realized. Water was used as the sole solvent. Multisubstituted vinyl sulfones were easily prepared with excellent alkyl group tolerance. A mechanism involving nucleophilic attack of a sulfinate anion was proposed.
