Fluorodenitration of activated diphenyl sulphones using tetramethylammonium fluoride

Article abstract of DOI:10.1016/0022-1139(94)03117-I

Fluorodenitration of nitro-substituted diphenyl sulphones occurs readily in dipolar aprotic solvents using tetramethylammonium fluoride as the source of fluoride, although other reactions including fluorodesulphonylation can sometimes occur in competition. - Keywords: Fluorodenitration; Diphenyl sulphones; Tetramethylammonium fluoride; NMR spectroscopy; Mass spectrometry
